Abstract

Some basic principles of angle-tuned magnesium oxide doped lithium niobate (MgO:LiNbO₃) critically phase-matched optical parametric oscillators pumped by Q-switched Nd:YAG 1.064μm pulsed lasers have been analyzed theoretically. The permissibility of parametric spectral tuning based on angle tuning the nonlinear MgO:LiNbO₃ crystal has been derived algebraically and discussed systematically. Based on these theories, the phase matching type and crystal orientation were chosen. The experimental achievements of 3 to 5μm angle-tuned MgO:LiNbO₃ critically phase-matched optical parametric oscillators pumped by Q-switched Nd:YAG 1.064μm pulsed lasers were demonstrated and the experiment results matched well with the theories.
