Intracavity self-focusing in a thin two-photon absorber acts, in combination with pinholes, as an efficient power and energy limiter in flashlamp (pulsed) and arc lamp (CW) pumped actively passively mode-locked crystalline Nd-doped lasers. Power limiting by the intracavity two-photon absorber is exploited to create the condition for optimum pulse compression in the saturable absorber. Additional pulse shortening is due to the elimination of the pulse tail by self-defocusing in the nonlinear crystal. Extracavity and intracavity measurements, as well as three-dimensional computer simulations, give a complete understanding of the pulse evolution in the cavity, including the two mechanisms of pulse shaping and compression

Abstract

Intracavity self-focusing in a thin two-photon absorber acts, in combination with pinholes, as an efficient power and energy limiter in flashlamp (pulsed) and arc lamp (CW) pumped actively passively mode-locked crystalline Nd-doped lasers. Power limiting by the intracavity two-photon absorber is exploited to create the condition for optimum pulse compression in the saturable absorber. Additional pulse shortening is due to the elimination of the pulse tail by self-defocusing in the nonlinear crystal. Extracavity and intracavity measurements, as well as three-dimensional computer simulations, give a complete understanding of the pulse evolution in the cavity, including the two mechanisms of pulse shaping and compression

Applied Physics/Condensed Matter/Materials Science encompasses the resources of three related disciplines: Applied Physics, Condensed Matter Physics, and Materials Science. The applied physics resources are concerned with the applications of topics in condensed matter as well as optics, vacuum science, lasers, electronics, cryogenics, magnets and magnetism, acoustical physics and mechanics. The condensed matter physics resources are concerned with the study of the structure and the thermal, mechanical, electrical, magnetic and optical properties of condensed matter. They include superconductivity, surfaces, interfaces, thin films, dielectrics, ferroelectrics and semiconductors. The materials science resources are concerned with the physics and chemistry of materials and include ceramics, composites, alloys, metals and metallurgy, nanotechnology, nuclear materials, adhesion and adhesives. Resources dealing with polymeric materials are listed in the Organic Chemistry/Polymer Science category.
