Yb:YAG晶体自调Q激光钛宝石激光器 Cr Cr Yb:YAG crystal self-Q-switched Ti:sapphire laser

摘要

用连续的钛宝石激光器作为抽运源,在室温下首次实现了Cr,Yb:YAG晶体的自调Q激光输出。在激光实验过程中,获得了在1.03 μm平均功率为75 mW和脉宽(FWHM)为0.4 μs的自调Q激光。激光实验表明了Cr,Yb:YAG晶体的确把Cr4+离子的可饱和吸收特性和Yb3+的激光增益特性结合到了一起,实现了自调Q激光输出,使得Cr,Yb:YAG晶体将成为一种新型的有发展前景的全固化的自调Q激光晶体。

Abstract

Using CW-Ti: sapphire laser as pumping source, the self-Q-switched Cr, Yb:YAG laser has been demonstrated at room temperature. An average output power as much as 75 mW at 1.03 μm with a pulse width (FWHM) as short as 0.4 μs was attained. The laser experiment demonstrated that the Cr,Yb:YAG crystal exactly combines the Cr4+ saturable absorber and Yb3+ gain medium into one. And Cr,Yb:YAG crystal can be a most promising self-Q-switched laser crystal for compact, efficient solid-state lasers.
