The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is really a exceptional substance that performs an important role in laser technologies. Its Major operate is always to create ultrashort pulses of light, spanning just a few hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light-weight absorption at about 981 nm can make the crystal compatible for diode pumping. It is additional enhanced by its impressive efficiency in this process, coupled with its low quantum defect.
FIG. four. Autocorrelation perform of the heart beat 共a兲and spectrum 共b兲of a laser with an oblong Lively component for an output power of 700 mW. The width of
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to identical measurements of those chemical components up to 100% of Yb-doping might be attained. This special characteristic permits ytterbium to take the place of yttrium with virtually no disruption to the crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C army specifications, an adhesion take a look at included making use of a tape that fulfills LT-90 requirements onto the lens film layer. The tape was affixed totally after which eliminated vertically. This method was carried out three times, causing no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical functions owing on the presence of thulium ions, and thus the components can be further more studied within the scope of laser and luminescence applications.
Spatial composition of your beam as well as corresponding intensity profiles I in the output with the laser.

... Not merely the situation of crystal during the cavity but will also the amplification axis of crystal affects the laser Procedure drastically, because the absorption and emission cross sections of the crystal are quite unique in accordance with the orientation in the crystal.
