The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is really a outstanding materials that plays an important function in laser technology. Its Most important function is always to deliver ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
We existing a dual-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output ability as much as 24 W and pulse size of twenty ns,or as a regenerative amplifier with output electrical power up to 21 W and pulse duration beneath 200 fs immediately after compression of chirped pulses. Both lasers have exceptional beam excellent with beam parameter M2

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW because of the comparable measurements of such chemical factors as many as a hundred% of Yb-doping might be reached. This one of a kind attribute permits ytterbium to go ahead and take place of yttrium with nearly no disruption to your crystal’s lattice.
Following air drying and subsequent cleansing by using a cotton cloth soaked in Liquor, the film floor confirmed no signs of peeling or scratches.

... Not merely the posture of crystal inside the cavity but additionally the amplification axis of crystal affects the laser Procedure considerably, because the absorption and emission cross sections from the crystal are quite unique based on the orientation from the crystal.
