This book was released on 1972 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes a number of research projects concerned with the generation, measurement, and properties of picosecond laser pulses produced by mode-locked lasers. Topics discussed include a theory of the two photon absorption-fluorescence method of pulse width measurement, a statistical model of the mode-locking process that is capable of explaining many of the observed features, a comparison of the model with experimental results, experiments with time-resolved spectroscopy and experiments with a novel type of nonlinear optical element that is potentially useful for mode-locking.

Download or read book Ultrashort Light Pulses written by S.L. Shapiro and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soon after the invention of the laser, a brand-new area of endeavour emerged after the discovery that powerful ultrashort (picosecond) light pulses could be extracted from some lasers. Chemists, physicists, and engineers quickly recognized that such pulses would allow direct temporal studies of extremely rapid phenomena requiring, however, development of revolutionary ultrafast optical and electronic devices. For basic research the development of picosecond pulses was highly important because experimentalists were now able to measure directly the motions of atoms and molecules in liquids and solids: by disrupting a material from equilibrium with an intense picosecond pulse and then recording the time of return to the equilibrium state by picosecond techniques. Studies of picosecond laser pulses-their generation and diagnostic tech niques-are still undergoing a fairly rapid expansion, but a critical review of the state of the art by experienced workers in the field may be a timely help to new experimentalists. We shall review the sophisticated tools developed in the last ten years, including the modelocked picosecond-pulse-emitting lasers, the picosecond detection techniques, and picosecond devices. Moreover, we shall outline the basic foundations for the study of rapid events in chemistry and physics, which have emerged after many interesting experiments and which are now being applied in biology. An in-depth coverage of various aspects of the picosecond field should be helpful to scientists and engineers alike.

Available in PDF, EPUB and Kindle. Book excerpt: Este trabalho apresenta alguns estudos experimentais sobre a geração de pulsos óticos curtos com lasers semicondutores e a deteção desses pulsos. Descreve-se inicialmente a geração de pulsos elétricos curtos com geradores a transistor avalanche e chaves fotocondutivas. Foi desenvolvido um modelo de circuito equivalente para lasers multi-modos, que permite simular com precisão a resposta ótica do dispositivo para diferentes condições de alimentação. Foram também desenvolvidos transformadores de impedância de larga banda passante. Linhas de transmissão de diversos tipos e substratos de diferentes constantes dielétricas foram empregados. Comprovou-se experimentalmente a melhoria da resposta ótica do laser a pulsos curtos de corrente com o uso desses transformadores, comparada com os arranjos convencionais. Mostrou-se também experimentalmente que os transformadores aqui desenvolvidos proporcionam um aumento significativo na largura de banda de sistemas de fotodetetores rápidos. São apresentados resultados experimentais de geração de pulsos óticos curtos com lasers semicondutores, usando-se as técnicas de mode-locking e chaveamento de ganho. Finalmente são sugeridas algumas técnicas alternativas para a medição indireta dos pulsos gerados pelo processo de mode-locking, e são mostrados alguns resultados preliminares.

Available in PDF, EPUB and Kindle. Book excerpt: Detailed studies of ruby laser mode-locking with saturable absorbers were carried out. Oscillation in pure, low order transverse modes has been achieved and improvements in pulse duration and general reproducibility have been obtained by employing DDCI in optical contact with a laser cavity mirror. Anomalous quenching effects of two-photon fluorescence patterns in Rhodamine 6G and DPA have been extensively studies. Transverse mode-locking of the ruby laser has also been observed in a confocal cavity which also produced simultaneous transverse and longitudinal mode-locking. The saturable action of phthalocyanine dyes in the vapour phase has been studied and successful Q-switching of the ruby laser employing phthalocyanine vapour has been accomplished. (Author).
