Abstract:
An external resonance type laser module includes a quantum cascade laser, a MEMS diffraction grating configured to include a diffraction/reflection portion configured to diffract and reflect light emitted from the quantum cascade laser and return a part of the light to the quantum cascade laser by swinging the diffraction/reflection portion, and a controller configured to control driving of the quantum cascade laser. The controller is configured to pulse-drive the quantum cascade laser such that pulsed light of a second frequency higher than a first frequency at which the diffraction/reflection portion swings is emitted from the quantum cascade laser and a phase of the pulsed light changes each time the diffraction/reflection portion reciprocates m times (m: an integer of 1 or more).

Claim (Index 6):
An analysis apparatus comprising:\n the external resonance type laser module according to  claim 1 ; a photodetector configured to detect light output from the external resonance type laser module and transmitted through an analysis target; and a calculation unit configured to calculate an absorption spectrum based on a detection result of the photodetector, wherein the calculation unit is configured to calculate the absorption spectrum based on third data obtained by reversing first data obtained by the photodetector in one of a forward path period and a backward path period in swing of the diffraction/reflection portion with respect to time based on a point in time at which the forward path period and the backward path period are switched, and superimposing the first data on second data obtained by the photodetector in the other one of the forward path period and the backward path period.
