研制了一台能产生亚100 fs脉冲的腔稳SESAM锁模Cr ~（4+）：YAG激光器。锁定130兆赫的脉冲重复频率的氢脉泽参考频率合成器提供了一个30纳米宽的频率梳为1530纳米的波长区域。结合一对乙炔稳定的外腔二极管激光器，该激光器为确定乙炔跃迁频率提供了高精度测量工具。
A cavity stabilized, SESAM mode-locked Cr4+:YAG laser capable of generating sub-100 fs pulses has been developed. Locking the 130-MHz pulse repetition frequency to that of a hydrogen maser-referenced frequency synthesizer provides a 30-nm wide frequency comb for the 1530-nm wavelength region. In conjunction with a pair of acetylene stabilized, external cavity diode lasers, this laser provides a high precision measurement tool for the determination of acetylene transition frequencies.
