Observe the 915nm Infrared Invisible Laser

-

 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.

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
