Optical parametric oscillator threshold and linewidth studies
This paper presents a detailed study of the optimum design parameters for the LiNbO 3 parametric oscillator. Theoretical and experimental studies of the optical parametric oscillator (OPO) threshold parameters and of linewidth control are presented. Consideration is given to practical factors that limit OPO performance such as laser beam quality and crystal damage mechanisms. In addition, stable single axial mode operation is reported.
