【摘要】 本文对铜蒸气激光的偏振模式进行了理论和实验研究。探讨了偏振型脉冲光的特性,结果表明:脉冲光的平均偏振度在一定的功率范围内随输出功率增大而下降,随腔长缩短而增大;随损耗比M增大而增大。实验验证了上述结果,并得到平均偏振度为97.6％的激光输出。更多还原

【Abstract】 Theoretical and experimental study on the polarization modes are performed on copper vapour lasers. The properties of polarized pulsed light are explored and the results show that the average polarizability of pulsed light is decreased with the increase of output power within a certain power range, whereas it is increased with the shortening of. the cavity length, and increased with the increase loss ratio M. These results are verified experimentally, and an average polarizability of 97.6% has been obtained for the laser output.更多还原
