Abstract
Optical radiation from a laser diode is frequency modified through interaction with a nonlinear optical material in an external optical cavity. High efficiency frequency modification is achieved through the use of optical feedback from the external cavity to narrow the linewidth of the laser diode output and frequency lock the laser diode to the external cavity.
