  • Coherent Anti-Stokes Raman Scattering Microspectrometer
    Coherent Anti-Stokes Raman Scattering (CARS) was first reported in 1965 by Maker and Terhune1 as a method of spectroscopy for chemical analysis. The energy diagram of the process is depicted in Figure 1. CARS involve the interaction of four waves designated as pump (p), Stokes (s), probe (p
  • Advantages of Semiconductor Laser Diodes Versus Helium Neon Gas Lasers
    , the products would likely be five to ten times their current size. Laser diode modules have. also served users well in such demanding applications as Raman spectroscopy, fluorescence, confocal. microscopy, holography, LIDAR, and flow cytometry. In fact, laser diode modules can do virtually everything a. HeNe
  • Dispersive Raman Spectrometers
    Dispersive Raman spectrometers measure the wavelength and intensity of inelastically-scattered light. They use visible lasers, a grating, and charged-coupled detectors (CCD) to collect data. In most dispersive Raman spectrometers, the CCD is a silicon array. The laser acts as a light source

  • Femtosecond Verses Nanosecond Laser Machining: Comparison of Induced Stress and Structural Changes in Silicon
    in the nanosecond (NS) regime. In this paper,. we compare the results of micromachining a single crystal silicon wafer using a 150-femtosecond and a 30-nanosecond lasers. Induced stress and amorphization of the silicon single crystal were monitored using micro-Raman spectroscopy as a function

  • Pulse Testing of Laser Diodes
    ) and. Raman amplifiers may be tested up to 5A. The majority of pulse testing is. performed with 500ns to 1µs pulse widths at a 0.1% duty cycle. These test. conditions are driven by the desire to minimize the average power dissipation. while keeping test duration as short as possible. The rise and fall times
