Yb:KGW (Ytterbium-Doped Potassium Gadolinium Tungstate) Crystal is an excellent laser gain material with advantages over Nd-doped materials. Its broad emission range of 1023-1060 nm enables ultrashort pulse generation in the ps or fs range. The wide absorption band and high absorption at 980 nm allow efficient diode laser pumping. Compared to Yb:YAG Crystal, KGW offers a larger absorption cross-section, reducing the minimum pump intensity required for transparency in the quasi-two-level system. Heeger Materials provides high-quality Yb:KGW Crystal for advanced laser applications.
