一种适用于脉冲Nd3+:YAG激光器的新型横模控制谐振腔
A novel transverse mode control resonator for pulsed Nd3+:YAG laser
摘要
本文报道了一种新型横模控制谐振腔——圆形空心波导谐振腔。实验表明这种新型横模控制诣振腔与腔内加小孔光阑的横模控制谐振腔相比,有基模TEM∞输出效率明显增高和远场发散角大大减小等优点,文中对其限横模机理进行了分析和讨论。
Abstract
It is presented in this letter that a novel transverse mode control resonator (TMCR) can be constructed by using a stable resonator in oonjuction with a suitable hollow circular dielectric waveguide. In comparison with a TMCR with a pinhole, the energy conversion of the pump to TEM00 mode output is high and the beam fan field divergence is small. The mechanism of the novel TMCR is discussed and analysed.
