Abstract

We experimentally investigate the performance of a commercial tapered amplifier diode operating in a pulsed-current mode with a peak current that is significantly higher than the specified maximum continuous current. For a tapered amplifier rated at $500\mathrm{mW}$ of continuous power, we demonstrate $2.6\mathrm{W}$ of peak optical output power with $15\mathrm{mW}$ of injection light for $200\mu \mathrm{s}$, $7\mathrm{A}$ current pulses. Different failure mechanisms for the tapered amplifier, including thermal and optical damage, are identified under these conditions.
