The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is usually a outstanding content that performs a very important role in laser know-how. Its Most important purpose should be to produce ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light-weight absorption at all-around 981 nm tends to make the crystal compatible for diode pumping. It can be further enhanced by its impressive effectiveness in this method, coupled with its lower quantum defect.

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to very similar measurements of these chemical components up to a hundred% of Yb-doping may very well be reached. This special attribute permits ytterbium to take the position of yttrium with just about no disruption on the crystal’s lattice.
Adhesion Examination Compliant with MIL-C-675C military services requirements, an adhesion examination included implementing a tape that meets LT-90 specs onto the lens film layer. The tape was affixed entirely after which you can removed vertically. This process was performed thrice, causing no blistering or peeling.
Raman, luminescence and transmission spectra expose optical capabilities owing towards the presence of thulium ions, and thus the materials can be even more analyzed in the scope of laser and luminescence programs.
Tungstates have a tendency to own large Raman coefficients (�?Raman scattering). For that reason, they are able to create substantial Raman achieve at reasonable optical intensities. It is feasible to utilize the laser crystal alone being a Raman converter.

... Don't just the position of crystal within the cavity but additionally the amplification axis of crystal affects the laser operation significantly, because the absorption and emission cross sections of the crystal are quite different in accordance with the orientation with the crystal.
Due to Earlier detected destructive conduct which originated from the network you might be making use of, be sure to request unblock to internet site.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is often KYW Crystal a amazing materials that performs a vital function in laser technologies. Its Most important perform is always to deliver ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Question RP Photonics for any tips about tungstate lasers, like femtosecond lasers and superior-ability lasers.
