注入锁定铜蒸气激光器的时空、能量以及偏振特性

Temporal,spatial,energy and polarized properties of an injection-lccked copper vapor laser

采用P分量的偏振光注入到平行平面腔的铜蒸气激光器中,结果表明,与未加注入光时的振荡器比较,注入锁定铜蒸气激光器的输出功率提高了43％,P分量的偏振度从0.30提高到0.78,脉宽由36ns加宽到48ns,输出光的发散角显著改善,由7.8mrad降到1.1mrad,与注入光束基本相同。

We studied the temporal, spatial, energy and polarized properties of a copper vapor laser with plane-plane resonator into which a parallel polarized beam was injected. The results showed that comparing with the original oscillator , the output of such injection-locked copper vapor laser was increased by 43%, the degree of polarization risod from 0.30to 0.78, the pulse width was broadened from 36ns to 48ns, the divergence of output beam was improved remarkably from 7.8 mrad to 1.1 mrad and approximately equal to that of the injecting beam.
