Abstract

The absorption spectrum of formaldehyde at 1.573 μ m has been recorded at room temperature with a typical sensitivity of 6 × 10- 8 cm- 1 by using an off-axis integrated cavity output spectroscopy set-up based on a distributed feedback diode laser. More than 140 lines have been recorded within the laser spectral range (6351.3 - 6362.1 cm- 1). The corresponding spectral parameters (i.e. line positions and line intensities) are presented.
