Abstract
An external cavity diode laser and method of generating laser light comprising: generating light from a Fabry-Perot diode laser source; collimating light from the source with an intracavity optical element; reflecting light via a feedback mirror; and employing a diffraction grating to receive light from the optical element, diffract received light to the mirror in a non-zero order, receive reflected light from the mirror, and direct reflected light back towards the optical element and Fabry-Perot diode laser to complete an external cavity, the diffraction grating additionally directing a portion of the received light from the optical element toward a target.
