  • Abstract
    An external-cavity laser diode was frequency locked on the molecular absorption line R(3) of hydrogen iodide at 1.541 mum using the wavelength-modulation technique. Stabilization is realized by means of two feedback loops acting on two different frequency ranges. Measurements of the closed-loop error signal provided a relative frequency stability of a few parts in 10-10 in a 50-kHz acquisition bandwidth.
