We report what we believe to be the first demonstration of a multimode-diode-pumped gas laser: Rb vapor operating on the 795 nm D-1 resonance transition. Peak output of similar to 1 W was obtained using a volume-Bragggrating stabilized pump diode array. The laser's output radiance exceeded the pump radiance by a factor greater than 2000. Power scaling (by pumping with larger diode arrays) is therefore possible. (c) 2006 Optical Society of America.
