By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the equivalent measurements of those chemical aspects as many as a hundred% of Yb-doping may very well be accomplished. This special attribute permits ytterbium to go ahead and take area of yttrium with almost no disruption towards the crystal’s lattice.
The monoclinic crystal constructions results in a all-natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical options owing to the presence of thulium ions, and therefore the elements may very well be even more analyzed from the scope of laser and luminescence purposes.
A superior brightnessQ-switched oscillator and regenerative amplifier based upon a dual-crystal Yb:KGW laser
For tungstates, check here the ytterbium doping concentration can be quite high without the need of important quenching as the replaced ions have an exceedingly equivalent ion radius, as well as inter-ion distance is comparatively large.
Significant-energy repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes

Li2WO4-WO3 flux was efficiently utilized lessening the growth temperature beneath 900 oC. As outlined by one crystal x-ray measurements, the crystal corresponds to the P2/n Area group.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature ended up calculated. The emission spectrum and life span on the three File four excited state had been established. Employing typical and modified Judd–Ofelt theories, the depth parameters as well as radiative lifetimes were being calculated and superior settlement with the experimental results was attained for both of those theories.
Talk to RP Photonics for almost any guidance about tungstate lasers, like femtosecond lasers and high-electric power lasers.
