In functional phrases, the Yb:KYW crystal has observed its niche in higher-energy laser purposes due to its power to generate substantial energy ultrashort laser pulses though sustaining a compact dimension. The interaction of its attributes �?seamless ytterbium substitution, robust absorption characteristics, ultrashort pulse era and efficiency in Power conversion �?positions the Yb:KYW crystal to be a cornerstone in the laser engineering, masking varied fields ranging from scientific investigate to industrial applications.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is usually a remarkable product that plays an essential purpose in laser engineering. Its Main purpose should be to deliver ultrashort pulses of light, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in mild absorption at all around 981 nm helps make the crystal well suited for diode pumping. It really is additional Improved by its exceptional efficiency in this method, coupled with its very low quantum defect.

Optical structure of a laser with direct pumping Along with the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output of the radiation, WP is really a fifty percent-wave plate, CL is a collimating lens, FL is a concentrating lens, AE is really an Energetic factor created from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 would be the cavity mirrors, OC will be the output mirror, and SAM is a semiconductor saturable-absorber mirror.
Adhesion Exam Compliant with MIL-C-675C army expectations, an adhesion take a look at associated applying a tape that meets LT-90 specs onto the lens movie layer. The tape was affixed absolutely then taken off vertically. This technique was executed thrice, causing no blistering or peeling.

Nonetheless, after Nd3+:YAG became commercially readily available, the curiosity in CaWO4 dropped sharply. In afterwards several years, specific other tungstate crystals started to entice a lot of focus.
Though ytterbium-doped laser gain media frequently exhibit a little quantum defect, ytterbium-doped tungstates allow for particularly smaller values. Such as, a 1030-nm Yb:YAG laser would Commonly be pumped around 940 nm, While Yb:KGW or Yb:KYW might be most competently pumped all-around 981 nm.
Li2WO4-WO3 flux was correctly used minimizing the check here growth temperature under 900 oC. In accordance with solitary crystal x-ray measurements, the crystal corresponds to your P2/n House group.
