What Is Single Module CW Fiber Lasers?
Single module cw fiber lasers is a type of industrial laser cutting technology that uses the heat of a fiber laser for melting and removing the workpiece material, causing a clean cut. Laser stands for light amplification by stimulated emission of radiation.
Fiber laser technology uses a very narrow light beam on the target material. The light is focused by a moving system of optics in the laser machine.
There are many different types of laser generation methods. Fiber lasers are named so because they use an optical fiber as the active gain medium for light amplification.
The optical fiber medium is doped with rare earth elements such as neodymium, ytterbium, thulium, erbium, etc.

Types of Single Module CW Fiber Lasers
Laser source
Fiber lasers vary according to the material with which the laser source is mixed. Some examples include ytterbium-doped fiber lasers, thulium-doped fiber lasers, and erbium-doped fiber lasers. All these types of lasers are used for different applications because they produce different wavelengths.
Mode of operation
Different types of lasers release laser beams differently. Laser beams can either be pulsed at a set repetition rate to reach high-peak powers (pulsed fiber lasers), as is the case with "q-switched", "gain-switched" and "mode-locked" lasers. Or, they can be continuous, meaning that they continuously send the same amount of energy (continuous-wave fiber lasers).
Laser power
Laser power is expressed in watts and represents the average power of the laser beam. For example, you can have a 20W fiber laser, a 50W fiber laser, and so on. High-power lasers generate more energy faster than low-power lasers.
Mode
The mode refers to the size of the core (where light travels) in the optical fiber. There are two types of modes: single-mode fiber lasers and multi-mode fiber lasers. The core diameter for single-mode lasers is smaller, typically between 8 and 9 micrometers, whereas it is larger for multi-mode lasers, typically between 50 and 100 micrometers. As a general rule, single-mode lasers convey laser light more efficiently and have a better beam quality.
Application of Single Module CW Fiber Lasers

Generally speaking, ytterbium-doped single-module cw fiber lasers with an emission wavelength of 1064 nm are considered ideal for laser marking applications. These single-module cw fiber lasers can create permanent, high-contrast marks on plastics and metals. Both oems and suppliers require laser marking machines for part identification, such as barcodes, logos, or other text.
These machines can be manual or automatic and can be customized to accommodate short production cycles. In addition to marking, fiber laser equipment can also be used for annealing, etching, and engraving.
Laser cleaning
Single-module cw fiber lasers can effectively remove paint, oxides, rust, etc. From metal surfaces. This process is called laser cleaning. The process can be automated and customized to suit different production line parameters.
Laser welding
Another important application of these single-module cw fiber lasers is welding services. Fiber laser welding is one of the most promising emerging technologies that is rapidly gaining market share due to the various advantages the process offers. Laser welding is faster, more accurate, less deformed, higher quality, and more efficient than traditional methods.
Laser cutting
Laser cutting is one of the most researched areas of application for single module continuous fiber lasers. It can handle complex cuts with impressive edge quality. This makes it the best choice for parts with tight tolerances. Manufacturers are increasingly adopting it due to its numerous advantages. Let's see what those advantages are in the next section.
Components of Single Module CW Fiber Lasers
Fiber laser source
Fiber lasers use a fiber doped fiber optic cable as the laser source. There are many different types of rare earth materials available for doping. This leads to multiple options for fiber laser source. Ytterbium-doped fiber lasers are among the most common types of laser source among fiber lasers. Different doping materials produce laser of different wavelength.
Cutting head
The cutting head is the part that outputs the laser from the system and focuses it on the workpiece. It c a focus consists of a lens, a nozzle, and a focus tracking system. This is a movable part of the fiber laser cutting machine. The movement is according to the direction of the cut. The height of the cutting head from the workpiece is also adjustable.
Servo motor
Servo motor is the part responsible for the movement of the optics and mechanical parts of the laser cutting machine. Modern laser cutting machines have precise servo motors capable of minute movements of the optical components. The speed of the servo motor is also highly controlled. The precision of the laser cutting is largely dependent on the movement of the servo motor.
Cooling system
Laser machine parts generate a high amount of heat. Therefore, it requires a cooling system to ensure the internal components are not damaged. This job is done by the water chillers. Water chillers can drop the temperature of the entire fiber laser cutter very quickly.
Worktable
The worktable is the area for mounting the workpiece. The worktable, bed, and beam are collectively called the host. The host contains various servomotors for the relative movement in the z-axis.
Cnc controller
One of the benefits of a fiber laser cutting machine is its ability to be automated through a cnc control system. The cnc controller interprets the program instructions and passes it along to the various parts of the machine. The cnc controller moves the cutting head in the x, y, and z axis accordingly.
Assist gas system
The assist gas system is used to blow away the molten material from the workpiece. The laser beam is only capable of melting the workpiece material. Without the assist gas system, the molten material will cool-off and welding will take place. The assist gas system puts pressure on the molten material and pushes it away. The gas used may be oxygen, nitrogen, or air.
Control panel
Control panel is the interface where the operator can interact with the machine and adjust various settings. The control panel also has features like the emergency stop button. There is generally a display to preview the settings and learn about any error codes and messages.

How to Maintain Single Module CW Fiber Lasers
Clean the linear guide and add lubricating oil
The smoke and dust generated during the cutting process will harm the guide after a period of use, so it needs to be cleaned every day, and lubricating oil needs to be added after cleaning to ensure more precise cutting and higher cutting quality.
Adjustment of the synchronous belt
If the synchronous belt is too loose or too tight, it will cause the synchronous belt to wear. It is necessary to adjust the synchronous belt regularly to ensure stability. You can consult our technicians to get the appropriate tightness.
Water tank cleaning and circulating water replacement
Be sure to fill the laser diode with circulating water before starting the machine. The quality and temperature of the circulating water directly affect the service life of the laser diode. Clean the water tank and replace the circulating water regularly (recommended once a week).
Cleaning of the reflector and focusing mirror
After a period of use, smoke and dust will adhere to the surface of the reflector and focusing mirror, affecting the thickness, precision and quality of the cutting. Therefore, it is necessary to clean it with pure alcohol every week and use a professional cleaning cloth.

Future expansion
When setting up your maintenance schedule, consider future expansion plans. As your business grows, your cw fiber laser may experience a higher workload. Plan for possible upgrades and maintenance adjustments to accommodate increased usage and maintain cutting quality.
Fiber laser technology uses stimulated emission of radiation to produce a focused, high-power laser beam. A laser diode emits light, which is then sent to a fiber optic cable for amplification. When this powerful laser strikes the surface of a material, the high-intensity light is absorbed and converted into heat, melting the surface.
A high-speed gas stream parallel to the laser beam is used to blow away any molten material in order to cut the workpiece.
The first point of contact of a single-module continuous fiber laser with a material must be more intense than subsequent interactions, as the first contact must pierce the material rather than simply cut it. This requires using a high-power pulsed beam to punch a hole in the material, which lasts about 10 seconds for a 12 mm thick stainless steel plate. At the same time, the high-speed gas stream will clear away debris to display a clear output image.
Typically, single-module continuous fiber lasers use computer numerical control technology that allows cutting data to be received from a computer-aided design workstation. These technologies help control the material surface or the laser itself to produce specific patterns or designs.
Single-module continuous fiber lasers also have dual interchangeable platforms to simplify loading and unloading of materials. This feature enables a fast laser cutting process while maintaining accuracy and precision.
Single-module continuous fiber lasers are also easy to maintain. Parts rarely need to be replaced and adjusted, which reduces the maintenance burden and expense. In addition, single-module continuous fiber lasers use nitrogen during the cutting process, which can achieve faster, more precise, and cleaner cuts.
