Abstract

An External-Cavity Laser Diode was frequency locked on molecular absorption line R(3) of hydrogen iodide at 1.541 μm using the wavelength modulation technique. This molecular reference is very important in many fields like HD-WDW telecommunication system and interferometry. Preliminary measurements of the closed-loop error signal provided a relative frequency stability of 9.5 times 10^-10 in a 160 Hz acquisition bandwidth.
