660nm 1.8W Red Fiber Laser System Video

-

 What I'm going to talk about today is 660nm 1800mW fiber laser system. It supports 3 working modes, CW/TTL/Analog. In TTL/Analog modulation mode, an external modulation signal needs to be connected. In addition, the Lock crystal head cannot be pulled out. External signal Mod Input, no need to connect in CW working mode.

To adjust the output power by adjusting 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. In addition, the red STOP button is used for emergency stop, and it is not used under normal circumstances.



The optic fiber can be customized. Here is 1000μm SMA905 interface fiber. 100μm to 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%.

Fiber-laser in-band pumping enables novel 2 µm high-power short-pulse laser

Highly efficient high-power short-pulse lasers in the 2 µm wavelength range based on thulium (Tm3+)-doped materials have a variety of applications that include materials processing (such as polymer-to-metal joining), lidar, mid-infrared optical parametric oscillators (OPOs) that produce wavelengths up to 12 μm, and mid-IR supercontinuum generation. They also would enable direct coherent soft x-ray generation via high-order harmonic generation (HHG). For these applications, a light source with much higher conversion efficiency, average power, pulse energy, and shorter pulse duration is desirable. Now, Masaki Tokurakawa and colleagues at the Institute for Laser Science, University of Electro-Communications (UEC; Tokyo, Japan) have developed novel 2 µm high-power short-pulse lasers based on new technique of fiber-laser in-band pumping at 1611 nm and Kerr-lens mode locking with a new Tm-doped gain medium provided from the University of Hamburg by researcher Christian Kränkel.1, 2
