Latest Patents
Plaessmann's latest patents include a Multi-pass light amplifier. This invention is a multiple-pass laser amplifier that utilizes optical focusing between subsequent passes through a single gain medium. The design ensures a reproducibly stable beam size within the gain region. The amplifier features a confocal resonator or White Cell resonator, which includes two or three curvilinearly shaped mirrors facing each other along a resonator axis. An optical gain medium is strategically positioned on the resonator axis between the mirrors or adjacent to one of the mirrors. The first embodiment of the invention employs two mirrors, which may include adjacent lenses, configured to reflect a light beam passing through the gain medium toward the second mirror. A light beam translator is incorporated to adjust the light beam's position for each pass through the translator. The optical gain medium can be solid-state, liquid, or gaseous and may be pumped longitudinally or transversely. The second embodiment features a White Cell configuration with first and second mirrors facing a third mirror, and the optical gain medium is positioned at or adjacent to one of the mirrors. Additional features include defocusing means and cooling mechanisms for the optical gain medium to enhance performance.
