Cavity-enhanced absorption spectroscopy of methane at 1.73 mu m
The integrated cavity output spectroscopy technique has been applied to the study of methane near 1.73 mum using a tunable diode laser. We have shown that this simple approach produces accurate high resolution spectra and have achieved a detection sensitivity of 1.8 x 10(7) rights reserved. cm(-1) for mirror reflectives of 99.84%.
