The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is usually a extraordinary content that performs a significant function in laser technologies. Its Principal purpose would be to make ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
time. Crystals in the compound melts congruently at 1007 oC, however soften crystallization of top of the range crystal is unattainable on account of stage transition at ~920 oC. The highest seeded Remedy approach from

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW because of the identical dimensions of those chemical factors as much as a hundred% of Yb-doping could possibly be attained. This unique attribute permits ytterbium to take the spot of yttrium with practically no disruption into the crystal’s lattice.
The monoclinic crystal structures results in a organic birefringence, helping to stay away from thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical characteristics owing towards the existence of thulium ions, and for that reason the components could be even further researched within the scope of laser and luminescence purposes.
Spatial construction on the beam and the corresponding depth profiles I for the output of your laser.

... Not merely the situation of crystal during the cavity and also the amplification axis of crystal has an effect on the laser Procedure significantly, as the absorption and emission cross sections on the crystal are quite diverse in accordance KYW Crystal with the orientation of the crystal.

Li2WO4-WO3 flux was successfully used cutting down The expansion temperature down below 900 oC. Based on single crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at home temperature were being calculated. The emission spectrum and life time of the three F four energized state had been established. Making use of normal and modified Judd–Ofelt theories, the intensity parameters along with the radiative lifetimes were calculated and very good settlement With all the experimental final results was attained for equally theories.
