Abstract
A spectroscopy system comprises a tunable laser including a gain chip, a collimating lens for collimating light from the gain chip, an end reflector, a focusing lens for focusing the collimated light on the end reflector, a thin film bandpass filter between the collimating lens and the focusing lens, and an angle control actuator for changing the angle of the thin film filter to the collimated light. The light from the laser is coupled into a sample cell providing a sample. An amplitude detector detects light from the tunable laser prior to passing into the sample cell and a sample detector detecting light from the tunable laser after passing through the sample cell. A processor controls the angle control actuator and monitors a time response of the sample detector and the amplitude detector to resolve an absorption spectra of the sample.
