In useful phrases, the Yb:KYW crystal has located its niche in substantial-electricity laser apps as a consequence of its power to generate high Power ultrashort laser pulses whilst keeping a compact dimensions. The interaction of its features �?seamless ytterbium substitution, sturdy absorption traits, ultrashort pulse generation and performance in Vitality conversion �?positions the Yb:KYW crystal as a cornerstone while in the laser technological innovation, masking varied fields starting from scientific study to industrial apps.

The comparison with glasses is acceptable since the large attain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.

time. Crystals of the compound melts congruently at 1007 oC, having said that melt crystallization of top quality crystal is difficult as a result of section transition at ~920 oC. The best seeded Remedy strategy from

The absorption and emission spectra of Yb:KYW Crystals Exhibit strong peaks at 980 nm and 1030 nm, respectively, making certain effective energy conversion and higher efficiency in laser methods.

Optical structure of a laser with direct pumping with the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output of your radiation, WP can be a fifty percent-wave plate, CL is a collimating lens, FL is often a focusing lens, AE can be an active component constructed from an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 are classified as the cavity mirrors, OC is the output mirror, and SAM is actually a semiconductor saturable-absorber mirror.

Adhesion Exam Compliant with MIL-C-675C army criteria, an adhesion exam involved applying a tape that meets LT-90 specifications onto the lens film layer. The more info tape was affixed completely then taken out vertically. This treatment was done 3 times, leading to no blistering or peeling.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are applied as lasing resources to deliver ultrashort (~ one hundred-two hundred fs) substantial electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser devices.

Tungstates are likely to possess large Raman coefficients (�?Raman scattering). For that reason, they might crank out important Raman get at average optical intensities. It can be done to utilize the laser crystal by itself being a Raman converter.

Nevertheless, the moment Nd3+:YAG grew to become commercially obtainable, the desire in CaWO4 dropped sharply. In afterwards years, specified other tungstate crystals started to bring in a great deal of notice.

The thermal conductivity of typical double tungstates is with the purchase to three–4 W/(K m) �?which isn't poor as opposed with other laser crystals (Despite the fact that several moments lower than for YAG), and rather large compared Together with the thermal conductivity of common glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is actually a impressive content that plays a crucial part in laser technological innovation. Its Main function is usually to make ultrashort pulses of light, spanning just a couple hundred femtoseconds.

Ask RP Photonics for almost any suggestions about tungstate lasers, like femtosecond lasers and higher-ability lasers.
