The DDS-based Multi-functional Spectrometer

We present a project of a new DDS-based multi-functional spectrometer and the results of its partial implementation. The proposed instrument may be rather quickly transformed from an absorption spectrometer to an emission one. Multi-functionality of proposed solution allows one to benefit from the strong features of different spectroscopic techniques depending on the goals of performed spectroscopic study. The emission spectroscopy techniques may be applied to reach the highest sensitivity or allow studying of non-stationary objects with a segmented chirped-pulse mode. The absorption spectroscopy techniques may be applied to reach the highest resolution and accuracy via Lamb-dip measurements or allow traditional studying of molecular spectra with Doppler-limited resolution.
