摘要: 采用简单的线性结构，首次实现了脉冲重复频率为GHz的克尔透镜锁模Tm:YAP激光器。实验中无需在谐振腔中加入任何附加器件，仅依靠晶体的三阶非线性效应即可实现锁模。在泵浦功率为7.27 W时，激光器已能在连续锁模状态下稳定运行。当泵浦功率增加至9.66 W时，在2068 nm处获得了2.80 W的最大平均输出功率，脉冲宽度为33.61 ps，重复频率高达3.04 GHz。这是Tm离子掺杂自锁模固体激光器的最大输出功率。该工作为在2 μm波段产生高功率、高重复频的超快脉冲激光提供了一种新的途径。
Abstract: A Kerr-lens mode-locked Tm:YAP laser operating at a gigahertz-level pulse repetition frequency was first demonstrated using a simple linear cavity configuration. Mode locking is achieved exclusively through the third-order nonlinearity of the crystal, without requiring any additional optical components in the resonant cavity. Stable continuous mode-locking operation is realized at a pump power of 7.27 W. When the pump power is increased to 9.66 W, a maximum average output power of 2.80 W is obtained at 1991.2 nm, with a pulse width of 33.61 ps and a repetition frequency as high as 3.04 GHz. This represents the highest output power achieved in self-mode-locked solid-state lasers doped with Tm ions. This work provides a new approach for generating high-power, high-repetition-rate ultrafast pulses in the 2 μm wavelength band.
