Abstract

High-power laser-diode arrays have been demonstrated to be viable pump sources for solid- state lasers. The diode bars (fill factor of 0.7) were bonded to silicon microchannel heatsinks for high-average-power operation. Over 12 W of cw output power was achieved from a one cm AlGaInP tensile-strained single-quantum-well laser diode bar. At 690 nm, a compressively strained single-quantum-well laser-diode array produced 360 W/cm² per emitting aperture under cw operation, and 2.85 kW of pulsed power from a 3.8 cm² emitting- aperture array. InGaAs strained single-quantum-well laser diodes emitting at 900 nm produced 2.8 kW pulsed power from a 4.4 cm² emitting-aperture array.
