Abstract

A period-doubling route to chaos with nonstationary transverse pattern is observed in a diode-pumped Nd:YAG laser with a Cr4+:YAG saturable absorber. The nonlinear behavior results from the multitransverse-mode competition with gradually adding the number of the transverse modes. By analyzing the transverse pattern, we find that the bifurcation accompanies with the increase of the higher-order family of transverse modes in sequence. Moreover, a series of period-doubling route to chaos beginning from the low period is attained by varying the pump power at specific cavity configurations.
