| 摘 要： | 利用两块Ⅰ类KDP倍频晶体级联的方式,研究了时间相位调制宽带激光的二倍频特性.实验获得了二倍频转换效率与入射基频光功率密度的关系,在基频光功率密度为1.6 GW/cm2时,最大二倍频转换效率达70％,接近理论模拟的结果.实验结果表明,在高功率密度和低功率密度基频光条件下,倍频光光谱宽度约为入射基频光带宽的一半,与理论计...

| Abstract: | By using two type-I cascaded crystals,the second harmonic characteristics of temporal phase modulated broadband laser was demonstrated.The relation between second harmonic generation(SHG) efficiency and incident fundamental light power density was presented,and the highest efficiency of adjacent 70% was achieved when the fundamental laser power density was 1.6 GW/cm2,which was in agreement with the theoretical simulation.The experimental results show that the SHG spectrum bandwidths of high power density an... |
