Abstract
NASA Langley Research Center (LaRC) is working on a prototype laser system for simultaneous measurement of CO2 and O2 for planned Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) mission application. For this purpose, 1571 nm spectral band for CO2 sensing and 1262 nm spectral band for oxygen sensing have been selected. In this paper, we discuss recent progress made in the development of single mode, compact and stable, seed laser technologies for CO2 and O2 transmitters. In particular, the development of an advanced distributed feedback laser (DFB) module master oscillator operating at 1571 nm, that is efficiently coupled to drive electronics and nano-cooling scheme in a single hermetically sealed package of volume less than 2" x 2" x 0.5", is presented.
