Abstract
A cavity ring-down spectroscope includes a ring-down cavity. A trigger detector is optically coupled within the ring-down cavity to generate a signal to indicate a desired radiation level in the ring-down cavity. A controller is coupled to the trigger detector to control light provided to the ring-down cavity. A ring-down time may then be measured.
