摘 要:
给出了氧碘化学激光器中，引射式气帘对激光器内各段压力与输出功率等参数的影响。研究结果表明：在COIL光腔中采用引射式气帘的作用方式，可以显著降低光腔段的总压损失，为激光器后的压力恢复系统减轻工作负荷；在高背压条件下，能够显著降低腔压，改善光腔静压的稳定性，提高激光器输出功率的稳定性。[著者文摘]

Abstract:
The mechanism of ejecting gas-shades of COIL was given. The effect of ejecting gas-shades on pressures and output power of COIL was studied. The result shows that by adopting the action modes of ejecting gas-shades in the optical resonator, the loss of stagnation pressure is remarkably reduced. The working load of the pressure recover system at COIL exit will be lightened. On high back-pressure condition, static pressure in the resonator is remarkably reduced then the stability of static pressure in the resonator is improved.[著者文摘]
