    Notes: Abstract The spherical aberration observed in the far-field diffraction pattern of a He−Ne laser beam traversing a silica plate locally heated by a CO2-laser is investigated. This leads to a thermooptical method suitable to evaluate the effective derivative of the refractive index and elastooptical method suitable to evaluate the effective derivative of the refractive index and elastooptical coefficient.

    Notes: Abstract The spatial-spectral characteristics of superluminosity of a high-pressure N 2 + laser have been studied both theoretically and experimentally. The observed characteristics are explained by using the concepts on emission of a thermal source that is limited in time and space.

    Fast frequency control of a cw dye jet laser (1979)
    Springer
    Applied physics 19 (1979), S. 181-184

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract For frequency stabilization of a cw dye laser a very fast reacting piezo mirror translator with 350 kHz lowest resonance frequency has been developed. If it is driven by appropriate control electronics it allows to suppress efficiently fast frequency changes of the jet stream dye laser. The remaining frequency jitter is 270 kHz rms for full-bandwidth detection; it drops to a few kHz if a filter time constant of 100 μs is used.

    The SRS line-shaped nonlinear resonance in consideration of flight effects (1979)
    Springer
    Applied physics 19 (1979), S. 225-229 
    Details
    ISSN: 1432-0630
    Keywords: 42.60 ; 32

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract We investigate the problem of nonlinear interaction of a gas of three-level atoms with the field of standing waves in the situation where the atomic free path length at the initial and final metastable levels is comparable with the transverse dimensions of the field. The standing waves are resonant to adjacent Doppler-broadened transitions. The case of fields of Gaussian profile is analysed. It has been shown that in the limiting case of large free path length the nonlinear resonance width is of the order of the inverse time of flight of an atom in the field. The first and second derivatives of resonance with respect to frequency are considered. It has been shown that in the situation of flight they contain narrow resonant structures with a width of the order of a homogeneous width of the forbidden transition between metastable levels.

    Simulation on intensity self-pulsation in cw semiconductor lasers (1979)
    Springer
    Applied physics 20 (1979), S. 67-73 
    Details
    ISSN: 1432-0630
    Keywords: 42.60 ; 85.60
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract Intensity self-pulsation in cw semiconductor lasers has been analyzed by computer simulation assuming saturable absorbing characteristics in the loss term of the rate equation. A loss decrease of about 1% due to the saturable absorber is capable of generating self-pulsation. The theoretical pumping dependence of the self-pulsation frequency is consistent with the experimental data. Reflected light in the range of 10−5∼10−3 reduces the self-pulsation. Reflected light of larger than 10−2, however, induces self pulsation whose frequency is locked with the round trip time. The contribution of spontaneous emission in the range of 10−4∼10−3 also reduces the self-pulsation, while 10−6∼10−5 is ineffective.

    Raman scattering resonances in separated fields (1979)
    Springer
    Applied physics 18 (1979), S. 217-220 
    Details
    ISSN: 1432-0630
    Keywords: 42.60 ; 32

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract The effects in separated standing-wave fields that are resonant to adjacent Doppler-broadened transitions of many-level atoms are studied. It is shown that due to coherent transfer, at large distances, of polarization on a forbidden transition between the initial and final metastable levels of atoms in a gas, light emission arises at combination frequencies. It is also shown that a resonance with the width reciprocal to the time of flight between separated fields is available in the Raman scattering and absorption line shapes.

    Notes: Abstract The spectral and laser characteristics of 14 CH3-, CF3-, and F-substitutedp-terphenyls have been investigated. 2,2″-dimethyl-p-terphenyl in cyclohexane solution exhibits a shortest tuned laser wavelength of 311.2 nm, thus extending the range of dye laser emission by 1000 cm−1 in the uv. Peak output powers of 1.5 MW and 14% conversion efficiency at 332 nm were obtained under KrF-laser pumping in an untuned cavity.
