Abstract :
Summary from only given. This paper describes an auto-aligned femtosecond laser system controlled by genetic algorithm (GA). Femtosecond lasers have been developed rapidly, and generation of sub 10-fs pulses has been achieved by Kerr lens mode-locking. However, for femtosecond lasers, it is necessary to consider the nonlinear effect because the nonlinearity in the cavity is enhanced as the peak power increases.
