不同脉宽激光和频产生蓝色超短激光的模拟研究
Ultra-short blue laser generation by sum-frequency of two lasers with different pulse width
摘要
Abstract
In order to get new femtosecond-laser, an aperiodic poled optical superlattice was employed during the sum-frequency generation process. The optimized structure of the quasi-phase matching optical superlattice was studied by means of the genetic algorithm. Femtosecond blue-light laser at 457nm can be generated through femtosecond pulse mixed with top-hat pump pulse in the aperiodic optical superlattice. The simulation results indicate that this technique give a new scheme for generating a new ultra-short laser through nonlinear frequency conversion.关键词
