报道了用三硼酸锂、β-硼酸钡和碘酸锂晶体作为非线性材料，实现连续锁模的钛铝(2)O(3)激光的高效频率转换。二次、三次和四次谐波产生的蓝光和紫外光可调至205 nm，变换受限脉冲和脉冲长度低于1 ps。获得了400 nm、272 nm和210 nm的最大平均功率(重复频率82 MHz)：700 mW、120 mW和10 mW。为了优化不同的频率转换过程，必须考虑群速度色散的影响。
Efficient frequency conversion of cw mode-locked Ti:A1(2)O(3) laser radiation using lithium triborate, beta-barium borate, and lithium iodate crystals as the nonlinear material is demonstrated. Second-, third-, and fourth harmonic generation results in tunable blue and ultraviolet radiation down to 205 nm with transform-limited pulses and pulse lengths below 1 ps. Maximum average powers (repetition rate 82 MHz) of 700 mW at 400 nm, 120 mW at 272 nm, and 10 mW at 210 nm were obtained. The effects of group-velocity dispersion have to be taken into account to optimize the different frequency-conversion processes.
