摘　　要：开展了高功率双掺杂浓度板条激光技术的理论与实验研究,通过分段掺杂有效降低了板条长度方向上的吸收抽运功率密度的不均匀性,显著提高了单个激光板条的平均储能密度,总储能提高了39%。当二极管总抽运功率为15kW时,3kW的种子光源通过双掺杂板条可提取5.16kW的功率,这个数值相比单掺杂板条增加了36%,且光光转换效率为34.4%,与理论预期基本相符。conducted length of enhanced, The theoretical and experimental, research on high power slab laser with dual doped concentration are By means of segmented doping, the non-uniformity in absorption pumping power density along the laser slab is effectively reduced, the average and the total energy-storage increases by 39% energy-storage density of single laser slab is obviously When the total pumping power of the diode is 15 kW, after passing through the dual doped laser slab, the 3 kW seed light source can extract a power of 5.16 kW, which increases by 36% if compared with that for single doped laser slab. The optical-to-optical conversion efficiency is 34.4%, which is basically consistent with the theoretical prediction.
