We report a novel technique for the synchronization of two different femtosecond solid-state lasers by crossing of both laser pulses in a Kerr medium. Stable dual-wavelength femtosecond pulses at central wavelengths of 820 and 1250 nm have been obtained. The tolerance of cavity-length mismatch is ~0.6mum , where the pulse widths of the Ti:sapphire and the Cr:forsterite lasers are 18 and 40 fs, respectively, at average powers of 600 and 110 mW. The typical timing jitter derived from the cross correlation is less than 3 fs.
我们报道了一种通过在克尔介质中使两个不同的飞秒固态激光器的脉冲交叉来实现同步的新技术。已获得中心波长为820和1250 nm的稳定双波长飞秒脉冲。腔长失配的容限约为0.6μm，其中钛宝石激光器和铬镁橄榄石激光器的脉冲宽度分别为18 fs和40 fs，平均功率分别为600 mW和110 mW。由互相关得出的典型定时抖动小于3 fs。
