我们报告了一种带有部分反射半导体可饱和吸收镜的被动锁模 Yb:Y2Ca3(BO3)4 (Yb:CYB) 激光器。在中心波长 1044.7 nm（半峰全宽 (FWHM) 8.1 nm）处获得了 244-fs 的最小脉冲持续时间和约 55 MHz 的重复率。在 7.0 W 的吸收泵浦功率下测得的平均输出功率达到 261 mW。据我们所知，这是飞秒 Yb:CYB 激光器的首次演示。
We report a passively mode-locked Yb:Y2Ca3(BO3)4 (Yb:CYB) laser with a partially reflective semiconductor saturable-absorber mirror. The minimum pulse duration of 244-fs with a repetition rate of ∼ 55 MHz has been obtained at the central wavelength of 1044.7 nm (8.1 nm full width at half maximum (FWHM)). The measured average output power amounts to 261 mW under the absorbed pump power of 7.0 W. To our best knowledge, this is the first demonstration of a femtosecond Yb:CYB laser.
