    Applied physics 34 (1984), S. 123-128 
    Details
    ISSN: 1432-0649
    Keywords: 42.55R ; 42.60D ; 42.65

    Topics: Physics
    Notes: Abstract Pulse-shortening and pulse broadening effects in passively mode-locked lasers are analysed. A steady-state pulse duration limit is calculated and compared with round-trip simulations. The numerical calculations apply to a picosecond Nd: glass laser. Methods of short-pulse generation are discussed.

    Ninth-order nonlinear polarization and vuv generation in Hg vapor (1984)
    Springer
    Applied physics 34 (1984), S. 171-173 
    Details
    ISSN: 1432-0649
    Keywords: 42.65 ; 42.80

    Topics: Physics
    Notes: Abstract Interference of resonant ninth-order and nonresonant seventh-order nonlinear polarizations in Hg atoms has been studied, and direct conversion of fundamental ir radiation into the vuv has been obtained. The interference has been observed in the form of a Fano-Boitler contour. The efficiency of generation by ninth-order processes appears to be higher than that by seventh-order.

    Bistability and passive Q-switching of a CO2 laser with saturable absorber (1984)
    Springer
    Applied physics 35 (1984), S. 77-82 
    Details
    ISSN: 1432-0649
    Keywords: 42.55 ; 42.65

    Topics: Physics
    Notes: Abstract The coexistence of bistability and repetitive passive Q-switching of a CO2 laser with a gaseous saturable absorber has been investigated experimentally. With CH3F as the saturable absorber bistability has been observed simultaneously with passive Q-switching, whereas with CH3OH either one of these phenomena can only exist, as demonstrated for the first time. The measured features of both systems can be explained qualitatively by rate-equation theory.

    Saturation of resonant frequency conversion processes in cadmium vapour (1984)
    Springer
    Applied physics 33 (1984), S. 225-234 
    Details
    ISSN: 1432-0649
    Keywords: 42.65
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We have investigated two-photon resonant up conversion of 375 to 159 nm coherent radiation using the four-frequency process ω159=2ω375+ω1040 in cadmium vapour, where the ir component (1040 nm) is internally generated by the 375 nm pump tuned to the Cd two-photon transition 5s 2 1 S 0→5s6s 1 S 0. Scaling laws and tuning behaviour of both the 159 and 1040 nm output power were measured up to 1×108 W cm−2 pump intensity and 2×1017 cm−3 Cd number density. The results are compared to numerical calculations based on semiclassical theory in a stationary perturbation approximation up to third order. Here, in accordance with experimental results, the ir component was assumed to originate from a superposition of stimulated emission and parametric generation. The observed saturation effects turned out to be mainly due to population changes of the atomic levels involved and are qualitatively reproduced by calculations. Discrepancies with respect to absolute output levels are discussed in terms of the approximations in the theoretical formalism.

    Off-resonant excitation of molecular vibrations in liquids, investigated by picosecond probe scattering (1984)
    Springer

    Notes: Abstract The coherent excitation of molecular vibrations in liquids via off-resonant stimulated Raman amplification is shown to consist of two parts with vastily different spectral and temporal properties. One component situated at the frequency differenceω L −eω S of the driving fields follows almost instantaneously the system response function. The second part at the eigenfrequency eω 0 carries information on the vibrational dephasing. Detecting both frequency components simultaneously by coherent anti-Stokes probe scattering a novel 2-channel method is demonstrated. The vibrational dephasing time of thev 3-mode of CH3I is directly measured to beT 2=2.6±0.15 ps. This result gives experimental support to the deconvolution techniques required in conventional spectroscopy.

    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.

    Collimation of atomic beams by resonant laser radiation pressure (1984)
    Springer

    Topics: Physics
    Notes: Abstract The application of the resonant light pressure created by an axially symmetrical light field for collimating atomic beams has been considered. As an example, consideration is given to the possibility of collimating an atomic beam by the light field produced by the reflection of a plane wave from the internal surface of a metal cone. It has been shown that the radiation pressure can reduce the atomic-beam transverse velocities to the value of the order of 100 cm/s which corresponds to effective temperature of about 10−3 K. A method for producing collimated beams of cold atoms based on simultaneous deceleration and collimation of atomic beams by resonant laser radiation pressure is proposed.

    Influence of dephasing relaxation on the transient properties of parametric four-wave mixing (1984)
    Springer

    Topics: Physics
    Notes: Abstract Transient parametric scattering is investigated theoretically using density matrix perturbation theory. Emphasis is placed on the effects of population and transverse or dephasing relaxation on the scattered parametric pulse durations. Pulse duration measurement provides important insight into the actual transient temporal behavior of four-wave mixing processes and is shown to be a potentially useful technique for the characterization of material time constants and incident pulse shape.

    Numerical study of energy transfer between a beam and its internal reflection component in a nonlinear medium (1984)
    Springer

    Topics: Physics
    Notes: Abstract A theoretical study is presented of a special case of stationary energy transfer in degenerate two-wave mixing in a reflection geometry. The two interacting beams consist of a beam and its first-order internal reflection component created at the boundary of a nonlinear medium. Numerical results obtained from the computer calculations are presented as graphs. It is found that, under suitable conditions, this phenomenon can be used to eliminate the multiple internal reflections.

    Notes: Abstract Anti-Stokes Raman laser experiments using metastable atomic Tl and Sn have been performed. The required metastable population inversion is generated by photodissociation of TlI and SnBr2 with KrF laser radiation. The Tl(Sn) system permits frequency up-conversion by 7793 cm−1 (17,163 cm−1). By optimization of system parameters, uv output energies up to 2.5 mJ (377 nm) and conversion efficiencies of more than 25% have been achieved for Tl. Further improvements and principal limitations will be discussed.
