915nm IR Diode Laser Coupled Fiber Optic

-

 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/Analog modulation mode, an external modulation signal needs to be connected.

The 915nm laser is an infrared laser, invisible light, we use an infrared sensitive film to observe. Faint light spots can also be photographed with a camera.

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
