Title Tunable Infrared Lasers for Gas-Phase Spectroscopy.

Personal Author S. R. Brueck
Abstract A broadly tunable, high power, continuous-wave, infrared laser suitable for molecular spectroscopy has been developed. The gain medium, based on type-II InAs:GaSb quantum wells, is adjustable from 2.5- to 12- m by adjusting the quantum well thicknesses. Tuning is achieved with a chirped distributed feedback grating, providing a simple, single adjustment tuning over an extended range. A tuning range of 65 nm has been achieved; much larger tuning ranges are possible, making the entire IR accessible with a small number of devices.
