Yb KGW crystal

opticallaser

Yb:KGW is already widely used laser active material to generate ultra-short pulses in range of few hundred femtoseconds. Large absorption cross section at around 981 nm makes the crystal well suited for diode pumping. Efficient absorption and low quantum defect let’s to build compact lasers for high power applications. • Material : Yb:KGW • Dimensions tolerance : +/- 0.1 mm • Surface quality : 10-5 S-D • Surface flatness : λ/10 @ 633 nm • Parallelism error : < 20 arcsec • AR/AR coatings : R < 0.5 % at 970-1070 nm *standard specifications
