The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is often a outstanding materials that plays a crucial position in laser know-how. Its Key purpose will be to make ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing inside of a regenerative amplifier by spectral profiling of the heart beat
The absorption and emission spectra of Yb:KYW Crystals Exhibit strong peaks at 980 nm and 1030 nm, respectively, ensuring effective Power conversion and large functionality in laser programs.
Optical layout of the laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output of your radiation, WP can be a half-wave plate, CL can be a collimating lens, FL is a focusing lens, AE can be an active aspect made from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC may be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
Adhesion Take a look at Compliant with MIL-C-675C military services requirements, an adhesion examination concerned making use of a tape that fulfills LT-90 specs onto the lens movie layer. The tape was affixed fully and after that removed vertically. This process was carried out 3 times, resulting in no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are utilised as lasing components to produce ultrashort (~ a hundred-200 fs) superior electric power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser systems.
