摘要：

A high-pulse-energy high-beam-quality tunable Ti:sapphire laser pumped by a frequency-doubled Nd:YAG laser is demonstrated.Using a fused-silica prism as the dispersion element,a tuning range of 740-855 nm is obtained.At an incident pump energy of 774 mJ,the maximum output energy of 104 mJ at 790 nm with a pulse width of100 μs is achieved at a repetition rate of 5 Hz.To the best of our knowledge,it is the highest pulse energy at790 nm with pulse width of hundred micro-seconds for an all-solid-state laser.The linewidth of output is 0.5 nm,and the beam quality factor M;is 1.16.The high-pulse-energy high-beam-quality tunable Ti:sapphire laser in the range of 740-855 nm can be used to establish a more accurate and consistent absolute scale of second-order optical-nonlinear coefficients for KBe;BO;F;measured in a wider wavelength range and to assess Miller’s rule q uantitatively.
