Abstract

Detection of CO, N2O, and CO2 in ambient air was performed with a room-temperature cw IR source based on difference-frequency generation in periodically poled LiNbO3. The source was pumped by a seeded high-power GaAlAs amplifier at 860 nm and a diode-pumped monolithic Nd:YAG ring laser at 1064 nm. The IR output was tunable between 2160 and 2320 cm−1 without crystal rotation. The CO detection sensitivity is extrapolated to 5  ppb m / Hz if limited by IR intensity noise.
