Abstract: A system for performing optical spectroscopy measurements includes a light source for generating an input optical beam and an interferometer. The interferometer includes a beam splitter that splits the input optical beam into first and second light beams; a first light path that directs the first light beam through a sample containing an analyte to a first output port; and a second light path that directs the second light beam to the first output port. At least one of the first and second light paths adjusts a relative phase of a corresponding one of the first and second light beams, so that the first and second light beams are out of phase at the first output port, substantially canceling background light and outputting sample light corresponding to a portion of the first light signal absorbed by the sample in the sample cell. A detection system detects the output sample light.

Abstract: An external cavity laser and method for operating same are disclosed. The external cavity laser includes a gain chip, a grating, an actuator and actuator driver. The grating diffracts light leaving the gain chip in a band of wavelengths back to the gain chip, the grating is characterized by an angle relative to light leaving the gain chip and distance from the gain chip, the angle and distance is controlled by the actuator. Part of the diffracted light is amplified by the gain chip. The actuator driver causes the angle to be dithered about an equilibrium angle in a motion characterized by an amplitude and average frequency. The amplitude of the dithering motion is chosen to either excite a plurality of adjacent laser modes of the gain chip or provide a servo signal for maintaining the grating angle at a target value.
