This study used the aspheric lens to realize the laser flat-top optimization, and
applied the genetic algorithm (GA) to find the optimal results. Using the
characteristics of aspheric lens to obtain the optimized high quality Nd: YAG 355
waveband laser flat-top optical system, this study employed the Light tools LDS (least
damped square) and the GA of artificial intelligence optimization method to
determine the optimal aspheric coefficient and obtain the optimal solution.
This study applied the aspheric lens with GA for the flattening of laser beams
using two aspheric lenses in the aspheric surface optical system to complete 80% spot
narrowing under standard deviation of 0.6142.
