Abstract :
Summary form only given. A two-mirror beam-shaping technique, applied to the output of diode bars has produced the near circular beams ideally suited to end pumping. Here we show that the same technique on be successfully applied to a broad-stripe diode, having a much smaller elongation of the emitter region than a diode bar. As a demonstration of its effectiveness we describe a Nd:YLF amplifier pumped by the shaped beam.
