An efficient frequency-converted solid state laser that outputs a single beam utilizing an angled reflector situated within the laser cavity. The laser comprises an optical cavity including a first reflector and a second reflector. A gain medium situated within the optical cavity is energized by a pump source to excite a laser emission at a fundamental wavelength. A nonlinear material is arranged within the optical cavity to convert the laser emission to a second wavelength. The angled reflector, which is reflective of the second wavelength and transmissive of the first wavelength, is situated within the optical cavity between the first reflector and the nonlinear material. In operation, the forward-propagating converted beam is reflected from the second reflector, and then combines with the reverse-propagating converted beam. The angled reflector reflects the combined beam so that it exits from the optical cavity at a nonzero exit angle. Typically, the angled reflector and the exit angle are selected so that the angled reflector reflects substantially all polarizations of the combined beam. In some embodiments, the angled reflector is formed on the nonlinear material. In other embodiments, the gain medium is coupled to a surface that comprises the angled reflector, such as an optically transparent heatsink. Some embodiments include means for reflecting the first converted beam from the second reflector so that the reflected first converted beam is approximately in phase with the second converted beam within the nonlinear material.
