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。
Abstract
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, sustainability, and pointing stability, including eleven measurable parameters.
