    Abstract: A microscope for CARS microscopy has means for generating a pump light beam and a Stokes light beam that can be directed coaxially through a microscope optical system onto a sample. A detector detects the detection light proceeding from the sample. The means for generating the pump light beam and the Stokes light beam contain a laser and encompass a microstructured optical element that spectrally broadens the light of the laser.

    Abstract: The present invention relates generally to the field of electrolytic and electroless metal plating. A method and system for determining the presence of analytes in metal plating solutions using Raman spectroscopy is described. High absorbance plating bath samples are analyzed by Raman spectroscopy by minimizing the penetration depth of the incident light beam. A chemical auto-dosing system for controlling the concentration of one or more plating bath additives in a metal plating bath is also provided.

    Abstract: Methods and systems for studying microscopic particles are provided. An optical trap for a selected microscopic particle can be formed with a laser beam at a first power level. The laser beam can have a variable power level associated therewith. The variable power level can be increased to a second power level. The laser beam at the second power level can produce Raman scattering signals. The second power level can provide sufficient excitation energy to the selected microscopic particle to produce Raman scattering signals and the second power level is higher than the first power level. A Raman spectrum can be detected from the Raman scattering signals produced by the laser beam at the second power level.

    Abstract: A method of monitoring sample crystallization from a solution. The method includes the collection of multiple Raman spectra from a sample dissolved in a solvent as a function of time and under conditions promoting crystallization. Within each of the multiple Raman spectra, a first signal is identified corresponding to the sample associated with the solvent. A second signal corresponding to the sample in a microcrystallite state is also identified. Thereafter, the intensity of the multiple Raman spectra are measured for an increase relating to formation of the sample in a microcrystallite state. A method of monitoring sample crystallization from a solution as a function of turbidity is also disclosed. The method includes the collection of multiple Raman spectra from a sample dissolved in a solvent as a function of time under conditions promoting crystallization. A decrease in intensity is measured across the multiple Raman spectrum over time, the intensity decrease associated with macroscopic crystallization opacity. The decrease in intensity is finely correlated with the onset of macroscopic crystallization of the sample from the solvent.

    Abstract: A micro-doppler ladar comprising a tunable laser to identify an unknown constituent of a gaseous cloud or region at a safe distance from the cloud or region. The tunable laser produces a laser beam tunable over a range of different frequencies. Each frequency produces a different vibrational response in the constituent in the gaseous cloud when the cloud or region is illuminated by the laser beam. A micro-doppler ladar system then interprets a back scattered beam to determine the induced vibrations. The determined induced vibrations can then be compared to known vibrations stored in a look-up table to identify the specific constituent(s) in the cloud or region.
