Yb:KGW

590.00600.00

Ytterbium doped Potassium-Gadolinium Tungstate crystal – This laser crystal is distinguished by broad spectral emission band 1023-1060nm which allows it to generate ps or fs laser pulses. Its wide absorption spectrum at 980 nm and high absorption of pump radiation allows an efficient use of diode laser pumping. Compared with YAG used as hosts for Yb3+, KGW has the advantage of larger absorption cross section, which decreases the minimum pump intensity wich is necessary to achieve transparency in the quasi-two-level system of ytterbium.
