| 摘 要： | 在理想位相锁定情况下,能够从轴对称折叠-组合腔CO2激光器系统中获得高功率、相干性好的输出光束.但失调现象不可避免,本文分析了折叠腔凹面全反射镜的失调对位相锁定效果的影响,并给出相应的数值计算值.结论表明当初始失调角度在一个容许范围内,仍然有很好的位相锁定效果.并且输出光强分布也很集中,进一步扩大了CO2激光器的应用范围.

| Abstract: | Under the condition of ideal phase-locking,high power and good coherence output beams from axisymmetric folded-combination(ASFC) CO2 laser can be obtained.Unfortunately,misalignments are inevitable.The influence of misalignment of the holophote of folded cavity on phase-locking is analyzed,and the correlative values by calculation are given.The conclusion is that the effect of phase-locking is still excellent when the misalignment angle is in the range of tolerance.And the distribution of the output light i... |
