KYW Crystal - An Overview
Blog Article
In simple conditions, the Yb:KYW crystal has found its specialized niche in high-power laser applications due to its power to deliver significant Electricity ultrashort laser pulses even though maintaining a compact sizing. The interaction of its functions �?seamless ytterbium substitution, powerful absorption properties, ultrashort pulse era and efficiency in Electricity conversion �?positions the Yb:KYW crystal like a cornerstone in the laser technological know-how, covering numerous fields ranging from scientific research to industrial purposes.

We present a dual-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output electrical power approximately 24 W and pulse size of 20 ns,or like a regenerative amplifier with output electrical power around 21 W and pulse duration under two hundred fs right after compression of chirped pulses. Each lasers have fantastic beam good quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Show robust peaks at 980 nm and 1030 nm, respectively, guaranteeing successful Electrical power conversion and superior overall performance in laser methods.
Ultrafast lasers, with pulse widths of a few picoseconds (10−12 s) or considerably less, empower time resolution necessary in laser-fired up fluorescence lifetime spectroscopy and imaging strategies.Furthermore, they deliver superior pulse peak powers at substantial repetition charges and moderate normal output powers.
Adhesion Exam Compliant with MIL-C-675C army specifications, an adhesion examination included making use of a tape that fulfills LT-90 requirements onto the lens film layer. The tape was affixed completely then taken out vertically. This technique was done 3 times, resulting in no blistering or peeling.

KYW Crystal (When you later retract your consent, We are going to delete Those people inputs.) As your inputs are initial reviewed with the writer, They could be posted with a few hold off.
Tungstates tend to get substantial Raman coefficients (�?Raman scattering). Thus, they might generate significant Raman gain at moderate optical intensities. It can be done to utilize the laser crystal alone for a Raman converter.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the identical measurements of these chemical features approximately 100% of Yb-doping may very well be reached.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at place temperature ended up calculated. The emission spectrum and life time with the three F 4 thrilled state were determined. Using standard and modified Judd–Ofelt theories, the depth parameters as well as radiative lifetimes ended up calculated and fantastic arrangement With all the experimental final results was obtained for both of those theories.
