摘要
为进行高能脉冲激光远场光束质量评价,从激光器、发射光学系统、光束控制系统和大气传输4个方面分析了光束传输与控制系统对远场光束质量的影响。在此基础上,综合考虑远场激光的时、空域参数,提出了一套光束质量评价指标体系,该指标体系包括远场激光的能量聚集度、能量均匀性、时间持续性和瞄准稳定性4个方面指标,共11个可实际测量的参数。
The effect of beam transmit-control system on the quality of far-filed beam is analyzed to evaluate high-energy pulsed beam quality in far-field, considering the laser energy source, emitting optical system, beam control system and atmospheric propagation. The quality evaluating system is proposed with four indexes as focus ability, uniformity, sustain- ability, and pointing stability, including eleven measurable parameters.
