The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is really a exceptional content that plays a significant job in laser technologies. Its Main operate should be to deliver ultrashort pulses of sunshine, spanning just some hundred femtoseconds.

Optical format of a laser with immediate pumping With all the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output on the radiation, WP is actually a 50 %-wave plate, CL can be a collimating lens, FL is a focusing lens, AE can be an active aspect produced from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 would be the cavity mirrors, OC could be the output mirror, and SAM is a semiconductor saturable-absorber mirror.
Adhesion Exam Compliant with MIL-C-675C military specifications, an adhesion take a look at included making use of a tape that satisfies LT-90 specifications onto the lens movie layer. The tape was affixed fully and after that eradicated vertically. This course of action was performed thrice, causing no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical capabilities owing for the presence of thulium ions, and so the elements can be further examined during the scope of laser and luminescence purposes.
