Paper Abstract

Spectrally-narrowed semiconductor laser diodes utilizing external volume gratings can be used to improve TEM00 power scaling and power conversion efficiency in diode-pumped solid state and fiber lasers. This approach is particularly attractive for pumping the narrow upper laser level of Nd:YAG DPSS lasers at 885 nm and the 1532 nm absorption band of Er:YAG DPSS lasers. While it is often believed that the use of such external gratings to wavelength lock diode lasers lead to unavoidable losses in power and efficiency, nLIGHT's proprietary laser designs and external volume grating integration techniques have eliminated these losses in our wavelength-locked diode laser products, enabling a broad range of spectrally locked laser diodes for pumping DPSS as well as fiber laser systems.
