    CARS-Background suppression by phase-controlled nonlinear interferometry (1990)
    Springer
    Applied physics 51 (1990), S. 49-51 
    Details
    ISSN: 1432-0649
    Keywords: 42.65

    Topics: Physics
    Notes: Abstract We have developed a new technique for efficient suppression of the nonresonant background in coherent anti-Stokes Raman scattering (CARS). The advantage of this technique, which is based upon phase-controlled superposition of an appropriately selected reference signal, is presented in theory and demonstrated experimentally by the example of the S(3) (pure rotational) transition of molecular hydrogen.

    High-temperature N2-CARS-thermometry (1990)
    Springer

    Topics: Physics
    Notes: Abstract N2-temperature measurements have been performed by coherent anti-stokes Raman scattering (CARS) up to more than 3200 K using a commercial heated graphite tube furnace. Surface radiation pyrometry served as the reference technique yielding good agreement between pyrometric and CARS-based temperature determination, resulting in an overall temperature uncertainty of ±80 K for a spectrum obtained at 1 bar and 3230 K.

    Interferometric enhancement of surface-generated second-harmonic radiation (1984)
    Springer
    Applied physics 34 (1984), S. 69-72 
    Details
    ISSN: 1432-0649
    Keywords: 42.65

    Topics: Physics
    Notes: Abstract Greatly improved second-harmonic emission has been obtained from dye monolayers adsorbed at quartz etalons. Two different types of interferometers have been studied in terms of the SH signal from dye coverage versus harmonic background emission. The phasematching-like conditions for constructive interferometric enhancement and the concomitant spatial and spectral emission characteristics are discussed in detail.

    Surface second-harmonic generation: A novel technique for ps-pulse duration measurements (1985)
    Springer

    Details

    Notes: Abstract Second-harmonic generation from dye adsorbates has been successfully used to measure the duration of ps pulses. In the red and in the blue-green spectral range pulse durations of 2.4 and 6.1 ps—in agreement with streak camera measurements — have been obtained from collinear, slow autocorrelation traces.

    Second-harmonic generation in centro-symmetric media (1987)
    Springer
    Applied physics 44 (1987), S. 5-10 
    Details
    ISSN: 1432-0649
    Keywords: 42.65
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We have studied the magnetic-dipole and electric-quadrupole contributions to second-harmonic generation (SHG) of centro-symmetric media. It can be shown that the phenomenological parameters α, β, γ can be arranged to form an effective $$\bar \chi _s^{(2)} $$ -tensor, which describes dipole-forbidden SHG as the effect of a surface layer upon excitation with a single plane electromagnetic wave. An experimental technique is proposed allowing a determination of the usually very small γ term due to magnetic-dipole interaction using coherent compensation of its contribution by a coverage with an appropriate dye monolayer.

    Notes: Abstract TheQ-branch spectra of molecular hydrogen have been used to determine rotational temperatures bycoherentanti-StokesRamanscattering (CARS). A supersonic jet expansion through a constant flow nozzle of adjustable temperature served as hydrogen source in the temperature range 300 to 2500 K. The analysis of the high-temperature data reveals details of the internal energy transfer in jet expansion.

    Notes: Abstract Using an excimer laser-pumped CARS spectrometer, single-pulse temperature measurements have been performed with a repetition rate of up to 80 Hz in a 3-dimensional, phase-matched geometry. Single-pulse temperature data measured in a furnace typically fluctuated by ± 50 K within the temperature range 300–1300 K. The CARS spectra were analyzed by the G-matrix formalism with inclusion of cross coherence effects.

    Notes: Abstract The rotational temperature behaviour in adiabatic jet expansion of molecular nitrogen is investigated over a wide range of stagnation density and nozzle diameter values using coherent anti-Stokes Raman spectroscopy (CARS). Estimates of rotational collisional numbers are made for both (N2+N2) and (N2+Ar) systems. The aspect of cluster formation for both systems is also discussed.

    CARS studies of vibrationally excited nitrogen at low pressures (1982)

    Notes: Abstract Coherent anti-Stokes Raman spectroscopy (CARS) was used to measure the vibrational temperature of microwave-excited nitrogen in a N2−CO−He mixture. CARS spectra, originating from the N2-vibrational levelsv=0 up tov=3, have been recorded by both narrowband scanning of the resonance region as well as by broadband OSA detection. For the microwave-excited N2 molecules a vibrational temperatureT v (N 2 = (2130±110K) and a lower limit of detection forN 2(v = 3) = 1.2 x 1015 cm−3 was established. The CARS results were independently confirmed by simultaneously recorded and spectrally resolved CO infrared fluorescence studies.
