A new high-perfomance Yb:CaAlGdO4 (Yb:CALGO) regenerative amplifier is demonstrated. Pumped by 116 W at ≈ 980 nm and seeded by means of a 92-fs oscillator, it generates as much as 36-W of average output power with chirped pulses, and 28-W with 217-fs compressed pulses at 500-kHz repetition rate. This corresponds to 56-μJ pulse energy and 258-MW peak power. The compressed pulses have a time-bandwidth product of 0.69 and could be further shortened with an improved compressor setup.

Abstract

A new high-perfomance Yb:CaAlGdO4 (Yb:CALGO) regenerative amplifier is demonstrated. Pumped by 116 W at ≈ 980 nm and seeded by means of a 92-fs oscillator, it generates as much as 36-W of average output power with chirped pulses, and 28-W with 217-fs compressed pulses at 500-kHz repetition rate. This corresponds to 56-μJ pulse energy and 258-MW peak power. The compressed pulses have a time-bandwidth product of 0.69 and could be further shortened with an improved compressor setup.

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.
