Abstract
The basic concept of an all-solid-state optical parametric oscillator (OPO) for the visible region of the spectrum is illustrated in Fig. 1. Here, an infrared solid-state laser is pumped using diode lasers, and the radiation it generates is then frequency-shifted by nonlinear processes into the ultraviolet for pumping a solid-state optical parametric oscillator that is tunable in the visible. We have been able to show that, even when only modest power/energy is available from the pump laser, tunable visible radiation may be efficiently produced despite the involvement of a number of nonlinear processes.
