建立了一种具有简单双元腔的飞秒Cr(4+):YAG激光器。该激光器在中心波长1540 nm处的典型重复频率为2.64 GHz，脉冲宽度为115 fs。输出脉冲采用二次谐波产生、分频光门控进行表征。锁模操作双元腔对中方便；此外，该腔体结构具有产生更高重复率的潜力，因为只需缩短增益介质长度即可使其小型化。
A femtosecond Cr(4+):YAG laser with a simple two-element cavity was built. This laser typically attained a repetition rate of 2.64 GHz with a pulse width of 115 fs at a center wavelength of 1540 nm. Output pulses were characterized by second-harmonic generation frequency-resolved optical gating. Alignment of the two-element cavity for mode-locked operation was easy; moreover, the cavity structure has the potential to produce an even higher repetition rate because one can miniaturize it simply by shortening a gain medium length.
