1. A subassembly for use in optical spectroscopy comprising:

  • a) an interferometer including optical components for receiving light and passing the light along a defined light path, the optical components including a beamsplitter separating the light into two portions and means for introducing a path length difference between the portions;

    b) a vertical cavity surface emitting laser, including electronics to drive the vertical cavity surface emitting laser to project a beam therefrom, operatively mounted with the interferometer with a portion of the beam generally following the defined light path and a portion of the beam interacting with a defined response element and then to a detector, the vertical cavity surface emitting laser including an operating parameter control system for controlling an operating parameter of the vertical cavity surface emitting laser responsive to a signal from the detector.
