Optical injection unlocking for cavity ringdown spectroscopy.

Continuous wave cavity ringdown spectroscopy requires a rapid termination of the injection of light into the cavity to initiate the decay (i.e., ringdown) event. We demonstrate a technique that accomplishes this through pulsed optical injection of a second laser into the main laser, resulting in 20-100 MHz frequency shifts in the otherwise cavity-locked main laser sufficient to create ringdown ...

Infrared Cavity Ringdown Spectroscopy of the Water Cluster Bending Vibrations

We report the first measurement of water monomer bending vibrations in gaseous (H2O)n clusters. Infrared cavity ringdown spectroscopy reveals discrete and sequentially blue-shifted bands near 6 μm for n ) 2-4 and unresolved broad features for n > 4, supporting both theoretical predictions and solid-state spectroscopy results. These measurements provide a measure of the monomer distortion that a...

Cavity Ringdown Laser Spectroscopy (CRDS):

Cavity Ringdown Spectroscopy has become a widely used technique in the optical absorption analysis of atoms, molecules, and optical components. The technique allows the determination of total optical losses within a closed cavity comprised of two or more mirrors, and can be made arbitrarily more sensitive by improvments in the cavity mirror reflectivity. Part of the great attraction that Cavity...
