Abstract
A new type of semi-conductor laser with composition InAsSb/InAsSbP is described. This laser was produced for the absorption spectroscopy of atmospherically important molecules in the 3100 cm −1 region and tested using a closed-cycle He-cryostat in the temperature range 30–80 K. The optimal characteristics of the laser were found to be a heatsink temperature of 62 K and a drive current range of 50–350 mA. Under these conditions, the laser emits single-mode radiation in an exceptionally large wavenumber range of >10 cm −1. To test the laser, several experiments were carried out in which the rovibrational absorption spectra of CH 3Cl, NH 3, OCS and H 2O were measured.
