摘　　要：采用自制的全固态高功率532nm单频绿光激光器端面抽运布氏角切割的钛宝石晶体,设计了紧凑、稳定、像散自补偿的嵌入式六镜环形谐振腔结构。通过调节抽运光与振荡光之间的最佳模式匹配关系,实现了高光束质量、高转换效率的900nm波段全固态单频可调谐钛宝石激光器。当抽运功率为15 W、输出镜在922nm处定点透射率为4.5%时,获得了平均输出功率大于2 W、波长可调谐范围为852~934nm的宽带可调谐单频红外激光器,3h内的功率稳定性优于±0.7%,光束质量因子M^2<1.04。By pumping the Ti：sapphire crystal cutted by the Brewster angle with a homemade all-solid-state highpower 532 nm single-frequency green laser,we design a compact,stable and self-compensating embedded six-mirror ring resonator structure.By adjusting the best mode matching relationship between pumping light and oscillating light,we establish an all-solid-state single-frequency tunable Ti：sapphire laser with high beam quality and high conversion efficiency at 900 nm.With the pump power of 15 W and the output mirror fixed point transmission of4.5% at 922 nm,the broadband tunable single-frequency infrared laser with average output power of more than 2 W and tunable wavelength range from 852 nm to 934 nm is obtained.The power stability is better than ±0.7% within 3 h and the beam quality factor M^2 is less than 1.04.
