High-efficiency, high-power, OPO-based RGB source

Summary form only given. We are developing a red-green-blue (RGB) laser-based source for projection display systems. Our design concept is to employ a high-pulse-rate, frequency-doubled Nd-doped solid state laser as the pump for a near infrared optical parametric oscillator (OPO). The OPO provides output at signal and idler wavelengths in the 900- and 1250-nm wavelength regions, respectively, which are doubled to provide blue and red wavelengths ideally suited for projection systems. The unused pump power provides the green wavelength. In this paper we report the latest results in scaling up the power of our RGB OPO to the multi-Watt level.
