The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is usually a exceptional substance that performs a vital role in laser engineering. Its Most important function is always to crank out ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light absorption at all-around 981 nm can make the crystal well suited for diode pumping. It truly is further Improved by its outstanding performance in this method, coupled with its very low quantum defect.
The absorption and emission spectra of Yb:KYW Crystals display robust peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Power conversion and substantial effectiveness in laser units.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW mainly because of the comparable measurements of these chemical features around a hundred% of Yb-doping might be realized. This distinctive characteristic permits ytterbium to go ahead and take place of yttrium with pretty much no disruption for the crystal’s lattice.
The monoclinic crystal constructions results in a all-natural birefringence, helping to stay away from thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and they are employed as lasing resources to make ultrashort (~ one hundred-200 fs) high energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser systems.
Tungstates have a tendency to possess substantial Raman coefficients (�?Raman scattering). Therefore, they're able to crank out substantial Raman obtain at reasonable optical intensities. It is achievable to use the laser crystal alone as a Raman converter.
For tungstates, the ytterbium doping concentration can be very substantial with out considerable quenching since the replaced ions have an exceptionally similar ion radius, as well as inter-ion distance is relatively significant.
