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.
Claims7
A cavity ring-down spectroscopy system, comprising:
- 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 measure an intensity of light leaked from the ring-down cavity.
A method of modulating a light beam in a cavity ring-down spectroscopy system, comprising:
- generating a light beam via at least one laser;
- extinguishing the light beam from the at least one laser via a first optical modulator;
- extinguishing the light beam from the first optical modulator via a second optical modulator;
- receiving the light beam attenuated by the second optical modulator in a ring-down cavity;
- and
- measuring a rate of decay of light leaked from the ring-down cavity.
