The 5-Second Trick For KYW Crystal
Blog Article
In functional phrases, the Yb:KYW crystal has located its niche in high-power laser applications because of its ability to deliver superior Vitality ultrashort laser pulses even though retaining a compact dimensions. The interplay of its features �?seamless ytterbium substitution, potent absorption characteristics, ultrashort pulse technology and performance in Strength conversion �?positions the Yb:KYW crystal as a cornerstone while in the laser technology, covering diverse fields starting from scientific study to industrial applications.
The comparison with Eyeglasses is suitable For the reason that large attain bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
The Yb:KYW crystal’s proficiency in mild absorption at all-around 981 nm tends to make the crystal compatible for diode pumping. It's even more enhanced by its amazing efficiency in this method, coupled with its small quantum defect.
For anyone who is attempting to obtain This web site applying an anonymous Personal/Proxy community, be sure to disable that and check out accessing web-site all over again.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW due to identical sizes of these chemical aspects as many as a hundred% of Yb-doping could possibly be reached. This exceptional attribute permits ytterbium to go ahead and take position of yttrium with virtually no disruption to the crystal’s lattice.
The monoclinic crystal buildings brings about a purely natural birefringence, assisting to keep away from thermally here induced polarization rotation and depolarization reduction.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are used as lasing products to crank out ultrashort (~ one hundred-two hundred fs) significant electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser units.
Tungstates are inclined to obtain high Raman coefficients (�?Raman scattering). As a result, they could generate considerable Raman obtain at average optical intensities. It is feasible to make use of the laser crystal itself like a Raman converter.

Substantial-power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps
When ytterbium-doped laser attain media generally exhibit a little quantum defect, ytterbium-doped tungstates allow for especially compact values. By way of example, a 1030-nm Yb:YAG laser would Commonly be pumped all over 940 nm, While Yb:KGW or Yb:KYW could possibly be most proficiently pumped close to 981 nm.
