High-brightness /spl alpha/DFB arrays at 915 nm and 1.06 /spl mu/m

Summary form only given. We present the first reported results for linear arrays of /spl alpha/DFB lasers in the 915 nm and 1064 nm wavelength regimes with record high brightness values. We also present results for a 2D array of /spl alpha/DFB lasers at 915 nm with a record high brightness using a novel stacking architecture. To our knowledge, this is the highest reported brightness from a multi-Watt semiconductor laser source and is over a factor of 5X higher than the accessible brightness of the highest-power broad-area bars reported to date. High-brightness laser diode arrays are attractive sources for applications such as soldering, heat treatment, marking and pumping of solid state lasers.
