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-powe r 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 extrapol ated to 5 ppb m/root Hz if limited by IR intensity noise.
