    Notes: Abstract A model concerning the generation of picosecond light pulses in solid state lasers is compared with existing experimental observations. The quality of selected single pulses and their favourable properties for investigations with ultrashort light pulses are discussed. Extensive physical applications of picosecond light pulses are reviewed. Emphasis is given to quantitative investigations of non-linear optics and of ultrafast relaxation processes in condensed matter.

    Notes: Abstract An optical modulator inside a laser cavity, if driven at the cavity c/2L frequency or a harmonic, will produce a variety of mode-coupled short-pulse and FM-laser phenomena. This paper reviews the kinds of CW and transient mode-coupling phenomena hat can occur in CW lasers and in selected lower-power pulsed lasers using either an active optical modulator or in some cases passive saturable absorbers.

    Notes: Abstract Experimental techniques for the generation of frequency-tunable picosecond pulses from passively mode-locked dye lasers are reviewed. Direct photoelectric measurements of pulse durations with a streak-camera of time resolution 〈3 ps are described. Recent studies of the build-up of pulse shortening and of saturable absorber photochemistry are discussed and related to the mode-locking processes in dye lasers.

    Notes: Abstract Many authors have reported disparate characteristics of pulses from Nd:glass mode-locked lasers. From these it has become clear that the well-developed pulse has a frequency sweep or subpicosecond structure and yields a contrast ratio less than the ideal 3 in the two-photon-fluorescence measurement. On the other hand, the early pulse is well behaved, has simple temporal and spectral structure, and yields a contrast ratio of 3 in TPF. The measurements are almost all indirect. Theories explaining the early pulse have appeared, but these fail for the fully developed pulse. The authors present time-resolved spectrograms, covering pulse development from 1/50 peak intensity, where the pulse is well mode-locked, to full development, where spectral structure is complex. A numerical analysis, including self-phase modulation, non-linear absorption, amplification and dispersion, yields results that qualitatively agree very well with the experimental records, suggesting that self-phase modulation plays an important role in the evolution of mode-locked pulses in a Nd:glass laser.

    Notes: Abstract Two-photon conductivity in GaAs and CdS0·5Se0·5 were investigated with modelocked Nd:glass laser pulse excitation, with a view to determine their suitability for picosecond pulsewidth measurement. The contrast ratio using GaAs as twophoton conductor was 1.8 and it increased to 2.4 when CdS0·5Se0·5 was used. The improved contrast ratio in the case of CdS0·5Se0·5 was partly due to the improved resolution of the crystal (2 ps) and partly due to the extended square-law region.

    Notes: Abstract Mode-locking of CW dye lasers are described. Three different methods: active mode-locking by acoustic loss modulation, pumping with mode-locked pulses and passive mode-locking by a saturable absorber, all resulted in stable continuous trains of tunable mode-locked pulses of various duration. Best results were obtained using passive mode-locking by a saturable absorber. The pulse lengths for this case were measured by auto-correlation technique to be as short as 1.5 ps. Factors influencing the mode-locking and possible improvements are discussed.

    Notes: Abstract Single light pulses, generated by a mode-locked Nd-glass laser, were shortened with saturable absorbers of low initial transmissionT 0. The pulse duration was reduced from 8 to 2.6 ps after a single pass through a dye cell ofT 0=10−7. Light pulses as short as 0.5 ps were observed after five transits through an absorberamplifier system. Detailed calculations of the stationary and the transient situation (with respect to the dye relaxation timeτ) are presented to demonstrate optimum conditions for the pulse shortening.

    Notes: Abstract We summarize a theory of self-induced transparency (SIT) which exhibits so-called ‘soliton’ solutions of the underlying equations, as the natural description of pulse evolution and break up. The theory is in remarkable agreement with recently published experimental work on87Rb vapour where transparent2Nπ pulses appear to break up into a train of 2π pulses.
