The output power is adjustable with an adjustment range of 0.5~5W. The adjustment accuracy is 1mW. The laser can also be controlled through software, and the communication interface is RS232. 1550nm is infrared invisible light, and the light spot can be observed with an infrared sensor plate. What is configured here is single-mode fiber, and polarization-maintaining fiber can be customized. The Line-width here is 3.7 MHz, and the line width of 1MHz can be customized.  This laser adopts DFB type laser chip , and cooperates with high-power gain optical path module to realize single-mode fiber output of single-wavelength high-power laser. The professionally designed drive and temperature control circuit control ensures the safe and stable operation of the laser, and the spectrum and...

 We are often exposed to infrared light, such as near-infrared wavelengths such as 780nm and 808nm, and the naked eye can see a faint red spot. As we all know, lasers like 915nm are invisible wavelength . So how do we detect it? Let's check it now. In the video below, we use a small infrared detection card to convert 915nm invisible light into visible light. The 915nm laser illuminates the observation card and displays a green visible spot.

 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.

 This is 1615nm infrared fiber coupled laser source . The Optical fiber is removable. Its optical fiber interface is FC/PC, and it can be customized. The 1615nm  laser is an infrared laser, which cannot be observed by the human eye. We use an infrared sensitive film to observe the light spot. The output power is 0~200mW adjustable by adjusting the working current. To adjust the working current, turn the 'Adjustor' knob clockwise, when the current exceeds the minimum working current, the Laser indicator light turns green, and there is laser output at this time. When the 'Adjustor' is rotated clockwise to the end, it is the max working current and the max output power of the laser.

 Today we are talking about 1030nm single-mode fiber coupled laser. The laser output power is adjustable from 100mW~1000mW, and the adjustment accuracy is 1mW. It can be adjusted by buttons. Customizable software control function, connect with computer via RS232-USB. Configured with single-mode fiber Hi1060, and can also customize polarization-maintaining fiber output.  1030nm is invisible light, we use infrared photosensitive film to observe the light spot. Let's check it now. This laser adopts all- fiber laser technology , professionally designed and driven temperature control circuit and control to ensure the safe operation of the laser and stable laser output power and spectrum. It is suitable as a seed laser for higher power laser systems, and can also be used for production testing of optical fiber devices. It can be provided in benchtop or modular packaging. Boot test. The power switch is on the back. Press the square button in the middle to enter the setting state. Th...

 This Micro ASE light source is CivilLaser newest product for 2022 and one of the smallest size ASEs on the market. It is smaller than the cell phones we use in our daily lives. The size of the ASE module is 50*50*15 mm. The flatness is ≤2dB. It powered by a DC 5V power adapter. The ASE module starts working as soon as power is applied. The test report and spectrogram of the ASE light source. The shock-proof packaging we ship.

 This is a 1064nm 15W high power infrared laser . An aluminum heat sink is installed under the laser module, which can effectively extend the continuous working time. The radiator is equipped with two cooling fans. There is a small power interface on the side of the data cable close to the laser head for the cooling fan. In addition, the Lock crystal head cannot be pulled out. External signal Mod Input, no need to connect in CW mode. The IR laser supports 3 working modes: CW/TTL/Analog. The following video demonstrates CW working mode. Let's check it now. This is a laser system that adjusts the power by adjusting the current. To adjust the current, turn the 'Adjustor' knob clockwise, when the current exceeds the min working current, the Laser indicator turns green, and there is laser output. 'Adjustor' rotates clockwise to the end, which is the max working current and the max output power of the laser. In addition, the red STOP button is used for emergency stop, ...

 This is 940nm 20W IR Laser Source . The laser head has a heat dissipation base, which can effectively extend the continuous working time of the laser. The radiator has two cooling fans. The back of the laser head and the power supply, the 3 working modes of the laser, CW/TTL/Analog are set from the back of the power supply. The 940nm laser is an infrared laser invisible to the naked eye, and a faint red light can be seen in the camera. But the energy is very strong. We shine a laser on the cardboard and it catches fire immediately. 20W is very high power laser , you need to wear IR laser protective glasses when operating, and do not use the laser to irradiate human eyes at any time. In addition, the red STOP button is used for emergency stop, and it is not needed under normal circumstances.
