The use of multiple transmitter beams is shown to significantly increase the peak focal-plane irradiance that can be achieved in the presence of thermal blooming. Computer simulation studies of the beam propagation problem show over a factor of 2 increase in the irradiance of a single beam and a factor of 9 increase when three coherent beams are focused on the same target spot. Preliminary experimental results with three mutually noncoherent, nonoverlapping beams are in qualitative agreement with the computer simulation.
结果表明，在存在热晕效应的情况下，使用多个发射光束可显著提高所能达到的焦平面峰值辐照度。对光束传播问题的计算机模拟研究表明，单束光的辐照度提高了2倍以上，当三束相干光束聚焦在同一目标点上时，辐照度提高了9倍。关于三束相互非相干、不重叠光束的初步实验结果与计算机模拟在定性上是一致的。
