Abstract :
A broad-area flared amplifier is fabricated that produces 5-W continuous-wave (CW) at 972 nm in a single-lobed, diffraction-limited far-field pattern. A high-power, tunable diode laser is used as the injection source. An incident power of only 90-120 mW is required to saturate the gain of the amplifier.
