Abstract
Near-IR and visible room-temperature diode lasers in broadly tunable external-cavity configurations are becoming commercially available for gas-sensing applications. Near 1.57 µm, a coincidence of overtone and combination-band transitions from CO, CO2, OH, and H2O is particularly interesting for combustion and combustor emissions monitoring. We report initial observations of the room-temperature absorption of CO and CO2 made with a commercial external-cavity diode laser.
