Contract: NNL07AA08C
Award Amount: $599,696.00
 

Abstract:

nLight developed high-power, high-efficiency laser diodes emitting at 1907nm for the pumping of solid-state lasers during the Phase I. The innovation brought to bear at 19-xxnm wavelengths nLight's design knowledge and experience from its highly successful 9xx-nm and 14xx-nm, high-efficiency and high-power laser diode programs. The expected performance for the laser at the conclusion of the phase I was 25% electrical-to-optical (E/O) conversion efficiency and 18 W continuous-wave power (CW) - both measured at 15C. The program was highly successful in achieving performance of 25W and 23% efficiency at 20C (5C warmer than projection). Such lasers meet the brightness and power requirements for the direct pumping of the quasi 4-level 5I7 to 5I8 transition in singly-doped Ho:YAG lasers. This work can readily be extended to 18xx-nm and 20xx-nm with comparable performance for application to the pumping of other solid-state lasers.
