The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a remarkable materials that plays a very important purpose in laser technology. Its primary function is to generate ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW a result of the similar measurements of those chemical features as much as one hundred% of Yb-doping could possibly be realized. This exclusive attribute permits ytterbium to take the spot of yttrium with just about no disruption into the crystal’s lattice.
Adhesion Examination Compliant with MIL-C-675C armed service standards, an adhesion check included implementing a tape that satisfies LT-ninety technical specs on to the lens movie layer. The tape was affixed absolutely and then eliminated vertically. This process was executed three times, resulting in no blistering or peeling.

Spatial structure of the beam and also the corresponding depth profiles I within the output of the laser.
For tungstates, the ytterbium doping concentration can be quite high devoid of important quenching since the changed ions have a really related ion radius, and the inter-ion distance is comparatively significant.
Higher-electric power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical programs
The thermal conductivity of common double tungstates is on the order to 3–4 W/(K m) �?which is not poor in comparison with other laser crystals (Though several times lower than for YAG), and reasonably significant when compared with the thermal conductivity of common glasses.
