Dm. Sonnenfroh et Mg. Allen, OBSERVATION OF CO AND CO2 ABSORPTION NEAR 1.57 MU-M WITH AN EXTERNAL-CAVITY DIODE-LASER, Applied optics, 36(15), 1997, pp. 3298-3300
Near-IR and visible room-temperature diode lasers in broadly tunable e
xternal-cavity configurations are becoming commercially available for
gas-sensing applications. Near 1.57 mu m, a coincidence of overtone an
d combination-band transitions from CO, CO2, OH, and H2O is particular
ly interesting for combustion and combustor emissions monitoring. we r
eport initial observations of the room-temperature absorption of CO an
d CO2 made with a commercial external-cavity diode laser. (C) 1997 Opt
