 This time we bring a 915nm high power semiconductor laser . The bottom of the laser module is equipped with a heat sink. Aluminum heat sink and cooling fan can effectively prolong the continuous working time of high-power lasers. There are three working modes of CW/TTL/Analog on the power supply for selection. The power of 60W is very high power, which can instantly ignite the cardboard. Be sure to pay attention to safety when operating, the operator must wear laser protective glasses, and the laser cannot point to other people or other flammable objects. 915nm infrared laser is invisible light, which is invisible to the human eye. Here the laser can easily ignite the cardboard.

 In the video is a 525nm 16W green high power semiconductor laser . A cooling module is added to the bottom of the laser head. This laser supports CW continuous working mode and modulation mode. The output power of the laser is adjustable from 0~16W, through the 'Adjustor' rotary button on the power supply. Here is the free space output mode, also custom fiber coupled lasers are available.  High power green laser.

 In the video below is a High Stability & Good Beam Profile 532nm 10W TEM00 laser . Its power supply with a touch screen, which can adjust parameters. And software control functions can also be customized. Let's check it now.  532nm DPSS green laser is made features of good beam profile, ultra compact, long lifetime and easy operating, which is widely used in collimation, laser medical treatment, scientific experiment, optical instrument, laser display, etc. The main features of this laser: High power, the actual output is 11.89W. Good stability, power stability is 0.733%. Good beam quality, transverse mode is TEM00, M² factor is 1.17. The laser test report. Laser Test Report.pdf Laser Instruction Manual.pdf

This is a 435nm 18W high power blue laser coupled optical fiber . Its fiber is pluggable. The Adjustor button on the power supply is used to adjust the working current, and the laser output power can be adjusted by adjusting the current. The laser supports CW continuous working and Modulation working mode, which can be adjusted by the slider button on the back of the laser power supply. Laser output without fiber optic installed. Here the optical fiber interface at the laser module end is FC/PC, align the buckle, insert the fiber, and tighten the fixing nut. Laser output after installing the optical fiber . Please go to CivilLaser learn more details about this 435nm 18W MM fiber coupled laser.

  808nm fiber-coupled laser uses PM fiber coupling , which has the advantages of high coupling efficiency and good output laser beam quality. The TEC temperature control system is used to ensure that the laser is more stable and has better performance. Compact structure, strong and reliable, suitable for various industrial and scientific research applications. This is 808nm 100mW infrared laser system coupled polarization-maintaining fiber . The working voltage is AC 90~240V and supports wide range voltage. Its laser power can be adjusted from 0~100mW, and it supports two working modes of CW/Modulation. 808nm is infrared laser, invisible laser, here use infrared sensitive film to observe the spot. The test report of 808nm 100mW IR PM fiber coupled laser system.

 Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with semiconductor laser , which is used to amplify laser signals in the 1030~1100nm band, Hi1060 single-mode fiber output, the output power is continuously adjustable, with high gain and low The advantage of noise. The desktop YDFA is convenient for experimental operation, and the user can adjust the pump current and output power through the buttons on the front panel. A more compact modular YDFA is also available, which is convenient for users' system integration. Both desktop YDFA and modular YDFA can support PC software control and serial port command control. What we are going to talk about today is 37dBm 5W single-mode YDFA and 40dBm 10W PM YDFA. First up is 5W SM YDFA. This fiber amplifier built-in 3 cooling fans.  The test report of YDFA-37-SM. The following is 40dBm PM YDFA. It's a high power polarization maintaining ytterbium-doped optical amplifier. Civil Laser's high power...

 This is 520nm high power green fiber laser system . This laser adds software control. Use RS232-USB to connect the laser and computer software.The laser output power can be adjusted by software. Using EasyHost software, you can also write your own programs to control the lower computer according to the communication protocol. The output power is 22W is a high-power laser, we added a heat sink under the laser module. The heat sink is composed of aluminum sheets and 3 cooling fans. Its fiber is pluggable, here we choose a 1000μm fiber. Let's check it now. Software Operation: Click 'Open COM', the software links the lower computer control circuit of the laser. When starting the software for the first time, set the maximum current first, and set a maximum current value according to the laser test report. If the current is too large, it is easy to burn out the laser chip. For each laser, the maximum current must be set first.
