利用Yb：YCa_4O（BO_3）_3锁模激光器实现了亚50 fs脉冲的直接产生。利用外部压缩，在1055 nm处产生短至35 fs的脉冲。振荡器工作在95 MHz的重复频率下，由两段分布布拉格反射器锥形二极管激光器泵浦，并由半导体可饱和吸收镜锁模。观察到脉冲光谱带宽超过40 nm（FWHM）的自拉曼转换的开始。
Direct sub-50-fs pulse generation is demonstrated with a mode-locked Yb:YCa4O(BO3)3 laser. With external compression, pulses as short as 35 fs are generated at 1055 nm. The oscillator operating at a repetition rate of 95 MHz is pumped by a two-section distributed Bragg reflector tapered diode laser and mode locked by a semiconductor saturable absorber mirror. The onset of self-Raman-conversion for pulse spectral bandwidths exceeding 40 nm (FWHM) is observed.
