Abstract

Q-switched Nd:YAG laser produces various nonlinear dynamical behaviors such as period doubling, quasi-periodicity, intermittency, and chaos according to the modulation frequency and pumping rate. Our Q-switched Nd:YAG laser shows quasiperiodic output near 5 kHz of modulation frequency. Since this quasiperiodic outputs are undesirable in the application to drilling and marking, they should be stabilized for desired periods, period 1T, 2T, etc. In this report we introduce the method of stabilizing them for the desired period by using the return map of laser output. Explaining the core of it and we present the experimental results in detail
