Abstract

Self-induced pulsations that are associated with atomic interference have been found in a laser-diode-pumped ${\mathrm{LiNdP}}_4{\mathrm{O}}_{12}$ microchip laser with an intracavity KTP frequency-doubling crystal operating in a $\mathrm{\Lambda }$ scheme. The instability and peculiar pulsations that were observed have been verified by a linear stability analysis and numerical simulation of two-mode laser equations, including nonlinear absorptions of a purely quantum nature and spontaneous-emission noise.
