我们报告的第一个演示，据我们所知，软孔径克尔透镜锁模在二极管泵浦的飞秒Yb 3+：YVO 4激光器。在中心波长为1050 nm处产生了短至61 fs的近变换极限脉冲，输出功率为54 mW，脉冲重复频率为104.5 MHz。据我们所知，这是由具有晶体基质材料的Yb激光器直接产生的最短脉冲。飞秒操作在吸收泵浦功率为190 mW时具有锁模阈值。Yb ~（3+）：YVO_4晶体的非线性折射率在1080 nm波长下分别为19 × 10 ~（-16）cm ~ 2/W和15 × 10 ~（-16）cm ~ 2/W。
We report the first demonstration, to our knowledge, of soft-aperture Kerr-lens mode locking in a diode-pumped femtosecond Yb3+:YVO4 laser. Near-transform-limited pulses as short as 61 fs are generated around a center wavelength of 1050 nm with an output power of 54 mW and a pulse repetition frequency of 104.5 MHz. This is, to our knowledge, the shortest pulse generated directly from an Yb laser having a crystalline host material. The femtosecond operation has a mode-locking threshold at an absorbed pump power of 190 mW. The nonlinear refractive indexes of the Yb3+:YVO4 crystal have been measured to be 19 x 10(-16) cm2/W and 15 x 10(-16) cm2/W for the sigma and pi polarizations, respectively, at 1080 nm.
