 In the past 2021, there was a great demand for 1064nm single-mode fiber lasers in the market. Most customers apply lasers in the field of scientific research, and they have relatively high requirements for the power stability of the lasers, and customers often ask us to provide a power stability test report that is more than 8 hours. Below is the 26-hour stability test data we did when the power of the 1064nm 100mW SM Fiber laser was adjusted to 43mW. Test instructions: This test eliminated interference factors as much as possible. 1.The laser, optical fiber, and power meter must be absolutely stable and not touchable, keep people away from the test area, and do not touch any part of the laser. 2. The optical fiber is directly connected to the optical power meter, and no adapter is used. 3. Eliminate the interference of the magnetic field near the laser. The basic parameters of 1064nm SM FC laser: The spectrum of 1064nm SM laser: Optical power meter for testing: ThorLab's optical

 It's a 638nm 30W high power fiber coupled laser system . There are CW/TTL/Analog 3 working modes available on the back of the power supply. When TTL/Analog is selected, external signal access is required. A radiator is added to the bottom of the laser head to extend the continuous working time of the laser. The heat sink under the laser head integrates 3 cooling fans.  The laser from optical fiber output port. We add a collimator on the fiber output port, the focal is adjustable. Turn on the laser and adjust the current of the power supply to adjust the output power of the laser. The strong red laser beam from collimator port.
