Tm:KYW Crystal | Thulium-Doped Potassium Yttrium Tungstate Crystal

Tm:KYW (Thulium-Doped Potassium Yttrium Tungstate) Crystal is a high-performance laser gain medium known for its broad fluorescence bandwidth, large emission cross-section, and relatively low upper-state lifetime. These properties make it highly suitable for femtosecond pulse generation in solid-state laser systems. As a biaxial double tungstate crystal, its optical characteristics must be described within its principal optical axes (Np, Nm, and Ng). Heeger Materials provides high-quality Tm:KYW Crystal to support advanced laser applications with reliable performance.
