    Notes: Abstract The laser-light field is shown to undergo a discontinuous order transition at the threshold for mode-locked pulses, accompanied by critical fluctuations below the transition point. These observations confirm theoretical predictions from the laser equations for a simplified model when incoherent interaction is included.

    Raman scattering and optical susceptibilities of Nd-doped glasses (1976)

    Notes: Abstract The absolute Raman scattering cross-sections of three Neodymium-doped glasses have been measured. These cross-sections have been used to determine the nonlinear optical susceptibility tensor of the three glasses. We have estimated the relative contributions of the “electronic” and “nuclear” nonlinearities to self-focusing index for linearly polarized light in these glasses. We have also performed numerical computations of the Hibert transform of our Raman scattering cross-sections, which are useful in the prediction of any other nonlinear effects.

    Power resonances in a Raman gas laser (1976)
    Springer
    Applied physics 11 (1976), S. 75-79

    Notes: Abstract The observation of a new type of resonance due to double-quantum transitions in the standing-wave field of a Raman gas laser is reported. A resonance dip with a width equal to that of the optically forbidden transition was experimentally detected in the output-vs-timing curve of a Raman Ne laser (λ=1.15 m) upon pumping by radiation of a He−Ne laser at 1.52 m. The theory presented shows that the resonance arises in the third order of perturbation theory when in resonant SRS the line is inhomogeneously broadened. The resonance can be considered as resulting from the overlap of dips in the velocity distribution of the nonlinear polarization induced by the standing laser wave.

    Unidirectional saturation spectroscopy, II (1976)

    Notes: Abstract The general probe absorption coefficient derived in Part I is specialized to homogeneous- and inhomogeneous-broadening limits and illustrated as the dipole lifetime is increased from 0 to values comparable to the level lifetimes. This progression reveals the relation between pulsation dips of the short-dipole lifetime limit and the dynamic Stark effect in general. Interpretations of the coherent interactions involved are given in terms of modulator and Raman effects and of dressed atoms. The single-probe unidirectional pulsation dip is shown to be a special case of the grating dip in which the fringe spacing becomes infinite. Analogies with three-level systems are given in which both two and three-level cases are seen to obey an “equal-area theorem”, and to involve level crossing. Some comparison is made with corresponding spectroscopy in which spontaneous emission provides the probe radiation.

    The waveguide laser: A review (1976)
    Springer

    Notes: Abstract The present article reviews the fundamental physical principles essential to an understanding of waveguide gas and liquid lasers, and the current technological state of these devices. At the present time, waveguide laser transitions span the visible through submillimeter regions of the wavelength spectrum. The introduction discusses the many applications of waveguide lasers and the wide variety of laser configurations that are possible. Section 1 summarizes the properties of modes in hollow dielectric waveguides of circular, rectangular, and planar cross section. Section 2 considers various approaches to optical feedback including internal and external mirror Fabry-Perot type resonators, hollow waveguide distributed feedback structures, and ring-resonant configurations. Section 3 discusses those aspects of molecular kinetic and laser theory pertinent to the design and optimization of waveguide gas lasers such as the scaling laws for discharge-excited gas lasers, molecular models useful in maximizing the oscillation bandwidth, the effects of gas flow rate, and the physics of optically-pumped far-infrared lasers. Finally, a review of the waveguide gas and liquid lasers reported to date is given in Section 4.

    Passive mode locking of a ruby laser using a birefringent crystal and a fractional-commensurate cavity length (1976)

    Notes: Abstract Mode-locked operation has been observed in a Q-switched, ruby laser using a quartz crystal as the passvie mode-locking element and a laser cavity length which is a whole fraction of that which is commensurate in mode-frequency spacing with the lowfrequency stimulated Brillouin scattering (lf S BS) in the crystal element. In addition, high-bit-rate operation has been observed, suggesting that the passive modulation of the lf S BS process is sufficiently strong to maintain a fixed-phase relation between several neighboring oscillating modes of the laser.

    Notes: Abstract We report on crystal processing, laser fabrication, emission spectra and output characteristics of neodymium pentaphosphate lasers. We obtained cw oscillation with an output power of 19 mW from a crystal with dielectric mirrors directly applied on polished (001) planes. We pumped longitudinally with 280 mW of an argon ion laser at 514 nm focussed to a 94-μm diameter. Near threshold our laser operated in the vicinity of 1053 nm; when pumped 1.6 times threshold it operated dominantly in the vicinity of 1063 nm.
