Abstract: An optical apparatus to provide several light bands on a single coaligned beam line or axis. The apparatus generally comprises five main components: a pump, a fold mirror, an input coupler, a nonlinear optical (NLO) crystal, and an output coupler. Alternatively, the present invention may comprise four main components, namely, a pump, an acute porro prism, a NLO crystal, and an input-output coupler. The pump input beam makes two passes through the nonlinear optical crystal and generates two new colors, having different wavelengths, during each pass through the nonlinear optical crystal.
