1480nm InGaAsP LOC broad-area-lasers with >18W pulsed output power at 20°C

Abstract

1480nm InGaAsP large optical cavity broad-area laser diodes were developed and optimized for pulsed operation showing optical output power of >18W at 20°C. Furthermore the μs pulse duration regime was investigated with respect to power saturation and self-heating at elevated operating currents.
