Title: Gerhard Spindler: Innovator in Laser Technology

Introduction

Gerhard Spindler is a notable inventor based in Waldshut-Tiengen, Germany. He has made significant contributions to the field of laser technology, holding 2 patents that showcase his innovative approach to laser amplification and solid-state lasers.

Latest Patents

One of his latest patents is a laser amplifier system. This system comprises a resonator with optical resonator elements that determine the course of a resonator radiation field propagating along an optical axis. The resonator is designed as a split resonator, featuring a first resonator section extending from a first virtual plane of separation and a second resonator section extending from a second virtual plane of separation. The resonator sections are optically dimensioned so that the resonator radiation field has radiation field states corresponding to the same resonator modes in each of the virtual planes of separation. An amplifying unit, which is optically independent of the resonator, is arranged between the two virtual planes of separation. This amplifying unit includes at least one laser-active medium and couples the radiation field states in a neutral manner concerning the resonator modes.

Another significant patent by Spindler is related to improving solid-state lasers, particularly solid-state disc lasers. This invention addresses the thermal lens effect that can distort the resonator radiation field. The proposed solution involves using at least one first adaptive mirror unit that compensates for the distortion caused by the thermal lens effect of the solid-state disc. The adaptive mirror unit can be configured using a heated glass sheet with an HR layer or through pressure-induced deformation using a fluid in an enclosed space.
