The gain bandwidth e.g. of Yb:KGW and Yb:KYW may be very massive when compared with that of Yb:YAG. This allows for broad wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values very well beneath one hundred fs happen to be attained with passive mode locking.

We existing a dual-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output electrical power approximately 24 W and pulse duration of twenty ns,or like a regenerative amplifier with output electricity up to 21 W and pulse duration underneath two hundred fs immediately after compression of chirped pulses. Both lasers have exceptional beam quality with beam parameter M2
Shade-coded reflectivity of a Bragg mirror for a function of wavelength and angle on the incident beam.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW due to identical measurements of these chemical aspects approximately 100% of Yb-doping might be reached. This exclusive characteristic permits ytterbium to take the place of yttrium with practically no disruption towards the crystal’s lattice.
Ahead of the event of Nd:YAG, Nd3+:CaWO4 was an important exceptional-earth-doped laser achieve medium. It had been in truth Employed in the primary consistently operating crystal laser.

Tungstates have a tendency to obtain superior Raman coefficients (�?Raman scattering). Consequently, they might make considerable Raman get at average optical intensities. It is possible to make use of the laser crystal by itself being a Raman converter.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of equivalent sizes of these chemical components approximately 100% of Yb-doping might be accomplished.
