 The 1550nm band single-wavelength laser (low power) adopts high-stability semiconductor laser chip , polarization maintaining  fiber output, professionally designed drive and temperature control circuit control to ensure the safe and stable operation of the laser, and can provide desktop or modular packaging. In the video below is a benchtop 1550nm 50mW 1MHz narrow linewidth laser. Let's check it now. The output power can be adjusted, and the adjustment accuracy is 0.1mW. It is a narrow linewidth laser with a spectral broadband <1MHz, kHZ level narrow linewidth lasers can also be customized. Software control function can be customized, using RS232 communication serial port. Default only supports button control. The standard version is controlled by buttons, control switches, and adjust the power. PM1550 polarization maintaining fiber is installed, and SM single-mode fiber can also be customized. The test report of 1550nm 50mW 1MHz Narrow Line-width PM fiber 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.

 This is our best selling laser module . Its pattern is composed of 81 grids and a center point. The laser focal length is adjustable, which is convenient for different working distances. The red module is shown in the video, and the green laser and blue laser can also be customized. Let's check it now.

 Usually we often see visible lasers, but few people will test infrared invisible lasers. Today we tested a 915nm infrared laser and its output power of 3000mW. Then when it is coupled through the fiber, what is the output power of the fiber end? Let's check it now. This is 915nm 3W IR semiconductor laser. It couples a pluggable optical fiber . The fiber can be customized. 100μm~1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the core diameter, the higher the coupling efficiency, usually the coupling efficiency is 80%~90 percent. In addition, the fiber length and interface also can be customzied. Here is 1000μm, SMA interface fiber. CivilLaser's solid-state lasers can be customized for fiber-coupled output.  The output power of the laser is adjustable from 0 to 3000mW, which can be adjusted by the knob. It supports 3 working modes, CW/TTL/Analog, switch the working mode on the back of the laser power supply. In TTL/...
