The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly massive as opposed with that of Yb:YAG. This allows for vast wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values well beneath one hundred fs are already realized with passive mode locking.

We existing a twin-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output ability up to 24 W and pulse duration of twenty ns,or for a regenerative amplifier with output power up to 21 W and pulse period underneath two hundred fs soon after compression of chirped pulses. Equally lasers have great beam top quality with beam parameter M2
Coloration-coded reflectivity of a Bragg mirror to be a function of wavelength and angle in the incident beam.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW a result of the identical dimensions of such chemical elements as much as 100% of Yb-doping might be achieved. This special characteristic permits ytterbium to take the place of yttrium with virtually no disruption to the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C navy benchmarks, an adhesion test included making use of a tape that fulfills LT-90 specs onto the lens movie layer. The tape was affixed fully and after that eliminated vertically. This method was carried out three times, causing no blistering or peeling.

Tungstates are likely to have high Raman coefficients (�?Raman scattering). As a result, they could make major Raman get at reasonable optical intensities. It is achievable to make use of the laser crystal by itself as a Raman converter.

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW a result of the equivalent sizes of such chemical factors as much as a hundred% of Yb-doping could possibly be accomplished.
The thermal conductivity of common double tungstates is on the order to 3–four W/(K m) �?which is not terrible in contrast with other laser crystals (Whilst numerous occasions fewer than for YAG), and pretty huge as opposed Together with here the thermal conductivity of usual glasses.
