time. Crystals of your compound melts congruently at 1007 oC, nevertheless soften crystallization of high quality crystal is extremely hard on account of period transition at ~920 oC. The very best seeded Resolution technique from
The absorption and emission spectra of Yb:KYW Crystals Screen strong peaks at 980 nm and 1030 nm, respectively, making certain economical Strength conversion and superior overall performance in laser systems.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to equivalent dimensions of these chemical components nearly 100% of Yb-doping may be obtained. This distinctive characteristic permits ytterbium to take the spot of yttrium with almost no disruption to your crystal’s lattice.
The monoclinic crystal constructions leads to a organic birefringence, helping to prevent thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and they are used as lasing elements to deliver ultrashort (~ one hundred-200 fs) higher electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser devices.
Tungstates have a tendency to obtain higher Raman coefficients (�?Raman scattering). For that reason, they will create sizeable Raman achieve at average optical intensities. It is feasible to make use of the laser crystal itself as being a Raman converter.

High-ability repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
Though ytterbium-doped laser gain media usually exhibit a little quantum defect, ytterbium-doped tungstates permit for notably small values. Such as, a 1030-nm Yb:YAG laser would Usually be pumped all around 940 nm, While Yb:KGW or Yb:KYW could be most successfully pumped all around 981 nm.

Simultaneously, a shorter laser wavelength could be obtained; it can be done to operate which has a quantum defect properly beneath one%. Being a consequence, the heat era can be so compact that this partly compensates the reduce thermal conductivity.
