Abstract
In this work, we report the absorption laser spectroscopy of iodine molecule in the 14600–14710cm−1 range, which was performed using a narrow linewidth diode laser, whose frequency is actively measured using a calibrated wavelength meter. Our signal-to-noise ratio is about three times greater than Salami and Ross (2005), allowing us to observe a total of 648 reference lines, 238 of which are new. The previous reported lines are in good agreement with the works carried out by Gerstenkorn and Luc (1979) and by Salami and Ross (2005). Our results also suggest that reference cells of more modest dimension should provide a viable signal for wavelength calibration and laser stabilization in this range.
