    Abstract: A compact, ultra-sensitive, inexpensive NIR spontaneous Raman spectrometer is presented. High sensitivity is achieved by the use of a multi-pass cell configuration combined with the electromotive properties of silicon crystal surface. A thin layer of silicon oxide chemisorbs molecules, which stick to its surface without altering their spectroscopic signatures. This new Raman spectrometer may be used to detect less than 40 ng (≈0.5 n mol) of ammonium nitrate deposited on the silicon surface with the signal-to-noise ratio better than 50 during 0.1 s recording time and for an illuminated area of 2×10−8 m2. These results may be useful in many areas, for example the foundation of an extended project to record the dissolved NO3− ions in a large river such as the Mississippi.

    Abstract: A miniaturized imaging system is provided that operates in multiple modes, including a coherent anti-stokes Raman scattering (CARS) mode. The imaging system includes: a laser delivery subsystem that generates an excitation signal; a scanning mechanism configured to receive the excitation signal from the laser delivery subsystem and direct the excitation signal through an optics subsystem onto a sample, such that the optics subsystem compensates for chromatic aberration in the excitation signal; and a dichroic mirror that receives emission from the sample in a backward direction and directs the emission along a collection path to a detector. The light source for the laser delivery subsystem may be a single femtosecond pulse laser.
