摘要
Abstract
CsLiB6 O10(CLBO)is a high-performance nonlinear optical crystal,particularly suitable for high-power ultraviolet laser by fourth harmonic generation(FHG,266 nm)and fifth harmonic generation(FIHG,210 nm).A CLBO crystal with the size of 120 mm×112 mm×62 mm was successfully grown using top seeded solution growth(TSSG)method in this work.The grown CLBO crystal exhibits a complete appearance without macroscopic defects such as cracking and visible scattering particles.A CLBO FIHG crystal component was cut from this crystal,and its UV-visible-near infrared transmittance,optical uniformity and weak absorption properties were analyzed in detail.The results include that,the mean transmittance exceeds 90%from210 nm to 1 800 nm,optical uniformity result is3.8×10-5 and the weak absorption is90×10-6 cm-1 at1 064 nm.All of these results indicate that the as-grown CLBO crystal possesses good transmittance in the ultraviolet region,high optical uniformity and low weak absorption,laying the foundation for subsequent research on related applications.关键词
