Optische Verstaerkeranordnung

DE 10327260 A UPAB: 20050217 NOVELTY - At least one of the beam-folding components (2, 2') is constructed for angular sensitivity, i.e. its reflectivity for a given angle of incidence exceeds that for predetermined undesired angles of incidence. USE - Beam-folding optical amplification equipment for a solid state laser. ADVANTAGE - High output power is achieved, making maximum use of the amplifying medium. At the same time, the amplified light has a high beam quality. In this design, despite multiple folding of the beam, occurrences of amplified spontaneous emissions (ASE) and parasitic oscillations, are suppressed as a result of the angular sensitivity.
