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 ...

Advantages and Disadvantages of Fiber Lasers

-
Image
Fiber laser  advantages : (1) The advantages of miniaturization and intensification brought about by the low manufacturing cost of glass optical fiber, mature technology and the availability of optical fiber; (2) The glass fiber does not require strict phase matching of the incident pump light like a crystal, which is due to the non-uniform broadening caused by the splitting of the glass matrix Stark, resulting in a wide absorption band; (3) The glass material has a very low volume-to-area ratio, and the heat dissipation is fast and the loss is low, so the up-conversion efficiency is high and the laser threshold is low; (4) The output laser has many wavelengths: this is because the rare earth ion energy level is very rich and there are many kinds of rare earth ions; (5) Tunability: Since the rare earth ion energy level is wide and the fluorescence spectrum of the glass fiber is wide. (6) Since there is no optical lens in the cavity of the fiber laser, it has th...
