Fascination About KYW Crystal
Employing our promotion offer, you can Show your logo, even further under your merchandise description, and these will been viewed by numerous photonics pros.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is really a outstanding material that plays a vital position in laser engineering. Its Main purpose will be to produce ultrashort pulses of light, spanning just some hundred femtoseconds.
time. Crystals with the compound melts congruently at 1007 oC, having said that soften crystallization of top quality crystal is difficult on account of period changeover at ~920 oC. The very best seeded solution approach from
The absorption and emission spectra of Yb:KYW Crystals Display screen solid peaks at 980 nm and 1030 nm, respectively, guaranteeing effective Electricity conversion and large overall performance in laser methods.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of identical dimensions of those chemical features nearly 100% of Yb-doping can be obtained. This special characteristic permits ytterbium to take the place of yttrium with practically no disruption to the crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C military services benchmarks, an adhesion test included applying a tape that satisfies LT-90 requirements onto the lens film layer. The tape was affixed totally after which removed vertically. This procedure was done 3 times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical features owing towards the existence of thulium ions, and therefore the materials can be further studied during the scope of laser and luminescence applications.

Substantial-ability repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps
Although ytterbium-doped laser attain media normally exhibit a little quantum defect, ytterbium-doped tungstates enable for specifically smaller values. One example is, a 1030-nm Yb:YAG laser would Commonly be pumped close to 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most competently pumped all around 981 nm.
This tandem of attributes has considerably-achieving implications, significantly in the construction of compact nevertheless powerfull lasers.

Concurrently, a shorter laser wavelength may be attained; it is feasible to function with a quantum defect properly below 1%. For a consequence, the warmth era might be so tiny this partly compensates the lessen thermal conductivity.
