The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is usually a amazing product that performs an essential purpose in laser technology. Its Key perform should be to deliver ultrashort pulses of light, spanning only a few hundred femtoseconds.
time. Crystals with the compound melts congruently at 1007 oC, nevertheless soften crystallization of top of the range crystal is not possible on account of section transition at ~920 oC. The very best seeded Option process from
The absorption and emission spectra of Yb:KYW Crystals Show powerful peaks at 980 nm and 1030 nm, respectively, guaranteeing efficient Strength conversion and superior effectiveness in laser devices.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to the related measurements of such chemical features approximately one hundred% of Yb-doping can be obtained. This special characteristic permits ytterbium to take the place of yttrium with almost no disruption for the crystal’s lattice.
The monoclinic crystal constructions brings about a purely natural birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra reveal optical capabilities owing to your existence of thulium ions, and as a consequence the supplies can be even more examined while in the scope of laser and luminescence applications.

Having said that, as soon as Nd3+:YAG grew to become commercially readily available, the interest in CaWO4 dropped sharply. In afterwards years, selected other tungstate crystals started to bring in a great deal of notice.

This tandem of attributes has significantly-achieving implications, specially in the construction of compact yet powerfull lasers.

Concurrently, a shorter laser wavelength could be obtained; it is feasible to operate with a quantum defect effectively under 1%. For a consequence, the warmth generation may be so compact that this partly compensates the lessen thermal conductivity.
