Description: Proposed is a high power, high efficiency, high reliability compact eye-safe LIDAR source. The diode pump source is an electrically series-connected array of single emitters coupled into an optical fiber known commercially as Pearl. During the course of the program nLight will transfer and improve its present record 1470-nm diode technology to a AuSn solder bond line, while also elongating the cavity for better performance. During the second phase of the program, internal gratings will be added to the diodes to narrow the emission line width providing better absorption in the Er:YAG system and a Er:YAG laser meeting the requirements set forth in the solicitation, pumped by the source developed over the course of the program's two phases, will be demonstrated.
