Ultrashort laser pulses are finding increasing application in numerous branches of science and technology. This article is an attempt to provide a comprehensive review of the whole field of ultrashort pulse generation, covering both the experimental and the theoretical aspects of the subject. By far the commonest method of generating pulses in the picosecond and subpicosecond regime is the technique known as 'modelocking' and it is with this that the review is therefore largely concerned. After introductory remarks and a simple treatment of some of the general principles, the central sections of the review deal with the main generic techniques, namely spontaneous mode-locking, active mode-locking (including mode-locking by synchronous pumping) and passive mode-locking. Within each section the material is organised into three main categories, namely ( a ) general background, ( b ) historical survey (mainly relating to experimental work and densely packed with references to published work) and (c) theoretical methods (presented with a strongly pedagogical flavour). A major section at the end deals with a mass of important (and mostly recent) work that does not fit naturally into the main framework of the review. This includes USP generation in semiconductor lasers, a number of special methods such as injection mode-locking (and others where two or more mode-locking techniques are combined), as well as chopping and switching techniques.

“…There are three points that must be made here, one being that the output of modern light sources (Bradley 1974) may well be narrower than an absorption line, particularly so in the case of complex molecular 'lines' involving massive vibronic interactions (Langhoff and Robinson 1974). Secondly, it is indeed the weak wings of absorption 'lines' that have to do with scattering and near resonance scattering, including the Raman effect (vide infra), and one must care about the exact shapes of such 'lines' in order to understand these problems quantitatively.…”

A unified theory of ordinary Rayleigh scattering, Raman scattering, and the absorption and reemission of light is presented and discussed from an experimental spectroscopist's point of view. Application to polyatomic molecules presents unique problems which are discussed. The theory should be able to account for experimental results off, near, and on resonance, using weak exciting light sources of various band shapes. The evolution of the Franck-Condon envelope on nearing the resonance region is described, and time dependent aspects of the interaction are treated in a general way. The theory in its present form cannot be used when the light source is so intense that population inversion, multiphoton effects, and stimulated processes take place.Une thkorie unifiee de ladiffusion Rayleigh ordinaire, de la diffusion Raman, et de l'absorption et reemission de lurnikre est presentke et discutke d'un point de vue de spectroscopie expkrimentale. L'application aux molCcules polyatomiques presente des problemes specifiques qui sont discutks. La theorie doit itre capable de rendre compte des resultats expkrimentaux loin de, prks de, et a la resonance, en utilisant des sources lumineuses excitatrices faibles de diverses distributions spectrales. L'tvolution de I'enveloppe de Franck-Condon en approchant de la regionde resonance est dCcrite, et les aspects des interactions, dependant du temps sont trait& de maniere genkrale. La thkorie presente ne peut pas Stre utilisee quand la source lumineuse est d'une intensite telle que surviennent: I'inversion de population, les effets a plusieurs photons, et des processus stimulks.[Traduit par le journal]Can.

Conventional laser panel displays are developed through the mass integration of electrically pumped lasers or through the incorporation of a beam steering system with an array of optically pumped lasers. Here a novel configuration of a laser panel display consisting of a non‐steered pumping beam and an array of electrically Q‐switchable lasers is reported. The laser oscillator consists of a robust, self‐standing, and deformable minute droplet that emits laser through Whispering‐Gallery Mode resonance when optically pumped. The laser oscillation is electrically switchable during optical pumping by applying a vertical electric field to the droplet. Electromagnetic and fluid dynamics simulations reveal the deformation of the droplet into a prolate spheroid under the electric field and associated attenuation of quality factor (Q‐factor), leading to the halt of the laser oscillation. A 2 × 3 array of droplets is fabricated by inkjet printing as a prototype of a laser panel display, and it successfully achieves the pixel‐selective switching of the oscillation.
