A platform has been developed for high-power, high-brightness, multi-single-emitter laser pumps for fiber lasers, directdiode, and other applications. Using multi-mode fiber with 105μm core and 0.22 NA, fiber-coupled optical power up to 100 Watts and a brightness as high as 100 kW/mm2/sr can be achieved. Common schemes for increasing brightness include spatial, wavelength, and polarization-beam combination of multiple single-emitters. Spatial multiplexing has been chosen for this platform to leverage JDSU's proven reliability of highpower single-emitter packages and passive optical components. In one configuration, we achieved >60W fiber coupled optical power, 50 kW/mm2/sr, and 45% wall-plug-efficiency using 105 μm core, 0.22 NA fiber from this platform. An optional VBG can also be placed inside the package for achieving spectral locking over a 16 nm wavelength range.© (2009) COPYRIGHT SPIE--The International Society for Optical Engineering.
