Book Description
In this thesis, an experimental investigation of harmonic generation from high-intensity laser-plasma interactions is presented. Harmonic experiments performed on the 1-terawatt FCM-CPA laser system at the University of Toronto, and on the 10-terawatt T3 laser system at the University of Michigan, are described. Using the FCM-CPA laser, various aspects of second harmonic generation were investigated systematically, with a focus on the effect of preformed plasma on harmonic generation. Experiments comparing harmonics generated by high-contrast pulses and by pulses containing weak prepulses show that the preformed plasma causes spatial and spectral breakup of harmonics and diffuses harmonic emission into large solid angles. On the T3 laser system, mid-order harmonic generation from various solid materials was studied and both odd and even harmonics up to the 7th were observed. Important features of harmonic generation, i.e., the laser-polarization dependence and the angular distribution of harmonic emission, were characterized. Pump-probe experiments were carried out as well on both laser systems by adding a controlled prepulse, which demonstrated a strong dependence of harmonic production efficiency on the gradient of preformed plasma. We also describe what we believe to be the first observation of regular satellite features accompanying the mid-order harmonics. Their dependence on target materials and on laser intensity was measured, and possible physical explanations are discussed. Besides, the development of the Toronto FCM-CPA laser system is summarized. Its original design and unique features are described in detail.

Ultrashort Light Pulses
Author: S.L. Shapiro
Publisher: Springer Science & Business Media
ISBN: 3662225743
Category : Science
Languages : en
Pages : 397
Book Description
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.
