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 of continuous power, we demonstrate of peak optical output power with of injection light for , current pulses. Different failure mechanisms for the tapered amplifier, including thermal and optical damage, are identified under these conditions.
