Abstract
An optical system and method that use a pump laser, an optical parametric oscillator, and two second harmonic generators to generate three colors of laser light. A recirculating optical sub-system includes a gain-guided optical parametric oscillator and one of the second harmonic generators and has four lenses that form two collimated optical beams between the optical parametric oscillator and the second harmonic generator.

An optical system comprising:
- an optical parametric oscillator (OPO);
- a second-harmonic generator (SHG);
- a first lens which passes light between the OPO and the SHG;
- a second lens which passes light between the OPO and the SHG;
- and
- a third lens which passes light between the OPO and the SHG.
