Paper Abstract

In this work we present latest results on mid-infrared GaSb gain chips as high-output power narrow-linewidth continuouswave single-frequency laser sources for ultra-widely tunable spectroscopy and sensing applications. More than 30 mW CW output power with over 100 nm / chip tuning and < 1 MHz linewidth performance is demonstrated in the entire band from 1900 nm – 2450 nm covering most essential absorption features from CO, CO2, NH3, CH4 and N2O for environmental and medical applications. Finally, we report on complete single-frequency laser system with integrated gain-chip for highresolution spectroscopy and sensor applications.
