The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is actually a outstanding material that performs a vital purpose in laser know-how. Its Major function should be to make ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
We present a twin-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output electrical power approximately 24 W and pulse duration of twenty ns,or for a regenerative amplifier with output electric power as many as 21 W and pulse length below 200 fs right after compression of chirped pulses. The two lasers have superb beam good quality with beam parameter M2
FIG. four. Autocorrelation function of the pulse 共a兲and spectrum 共b兲of the laser with an oblong Energetic ingredient for an output electrical power of seven-hundred mW. The width of
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to similar sizes of these chemical aspects as much as 100% of Yb-doping could possibly be reached. This exclusive characteristic permits ytterbium to take the location of yttrium with nearly no disruption for the crystal’s lattice.
Right after air drying and subsequent cleaning that has a cotton cloth soaked in alcohol, the film floor confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are employed as lasing resources to generate ultrashort (~ 100-two hundred fs) high ability pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser systems.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW a result of the identical measurements of these chemical elements nearly one hundred% of Yb-doping could possibly be accomplished.
