Lithium neodymium tetraphosphate lasers pumped via close-coupling to high-power laser diode arrays

With a pump power of approximately 250 mW, a TEM/sub 00/, multilongitudinal mode output power of 73 mW has been obtained from an external mirror device operating simultaneously on the two lines at 1047 and 1055 nm. Devices operating at 1317 nm have also been studied and a close-coupled, monolithic laser with an output power in excess of 28 mW has been demonstrated.<
