A nanosecond titanium sapphire laser with spectral linewidth Gamma(pl)~6 MHz and pulse energy of 50-100 mJ was demonstrated by using an intracavity electro-optic modulator to correct the frequency chirp in the output beam. The laser was referenced against a femtosecond frequency comb and used to measure the 6s-8s (F=4) two-photon transition frequency of Cs with a precision of 1.4 parts in 10(9).
通过使用腔内电光调制器来校正输出光束中的频率啁啾，展示了一种具有~6 MHz谱线宽度Gamma(pl)和50 - 100 mJ脉冲能量的纳秒钛宝石激光器。该激光器以飞秒频率梳为参考，用于测量Cs的6s - 8s（F = 4）双光子跃迁频率，精度达到10的9次方分之1.4。
