The Yb:KGW crystal is a high-performance laser gain medium developed specifically for high-power laser systems. Grown using the advanced Czochralski method, it exhibits exceptional physical and optical properties, making it highly valuable in ultrafast laser systems, industrial laser processing, and nonlinear optical research. With its uniquely broad absorption spectrum, Yb:KGW efficiently absorbs pump light in the 900-980nm range and converts it into high-energy laser output, making it particularly suitable for high-power, high-repetition-rate laser applications.
The Yb:KGW crystal offers outstanding thermal performance, with high thermal conductivity and a low thermal expansion coefficient ensuring excellent stability even under long-term, high-power operation. It provides a tunable laser output range of 1020-1080nm, delivering exceptional performance in both the near-infrared and mid-infrared regions. Its long fluorescence lifetime (approximately 300μs) enables efficient energy storage, making it particularly suitable for Q-switched and mode-locked laser applications. With these advantages, Yb:KGW stands out as an ideal choice for ultrafast laser systems, precision micromachining, spectroscopic analysis, and nonlinear optical conversion, where high stability, efficiency, and beam quality are essential.
Our Yb:KGW crystal products undergo strict quality control procedures, including optical homogeneity inspection, wavefront distortion testing, and laser damage threshold evaluation, ensuring superior reliability and consistent performance in demanding laser applications.
Precautions: To ensure optimal performance, it is recommended to store and operate the crystal in an environment of 25 °C with 40%–60% relative humidity. If surface contamination occurs, gently clean with 99% or higher isopropyl alcohol and lint-free optical tissue. Avoid using rough fabrics, water, or abrasive cleaners, as these may damage the coating or surface quality.
