Abstract
A laser diode with a low reflectivity output facet provides infrared light to a nonlinear crystal resonator such that a portion of the infrared light is converted to blue light. A mirror is located on the opposite side of the nonlinear crystal resonator from the laser. The mirror allows the blue light to pass, but reflects the infrared light exiting the resonator back through the resonator and into the laser diode. The laser diode is thereby locked at the resonance frequency of the nonlinear crystal resonator.
