Abstract
A cavity ring-down spectroscopy system and a method of modulating a light beam therein are provided. The cavity ring-down spectroscopy system includes at least one laser that generates a light beam, a first optical modulator positioned to attenuate the light beam from the at least one laser, a second optical modulator positioned to attenuate the light beam from the first optical modulator, a ring-down cavity positioned to receive the light beam from the second optical modulator, and at least one light sensor to detect an intensity of light leaked from the ring-down cavity.
