#CMT# #/CMT# The arrangement comprises two lenses (L1,L2) and polarization rotating unit, which are arranged between opposite end surfaces (1a,2a) of two stretched elements (1,2). The two stretched elements are made of an optical active material. The polarization rotating unit (QR) is formed between the former lens and the end surface of the stretched element. #CMT#USE : #/CMT# Arrangement for a laser system, particularly solid laser system and optical amplification device (all claimed), and for optical amplification of light beam. #CMT#ADVANTAGE : #/CMT# The arrangement enables strengthening of optical light, and avoids unfavorable effects of thermal lenses in an improved manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of the arrangement for optical amplification of light beam. 1,2 : Stretched elements 1a,2a : End surfaces L1,L2 : Lens QR : Polarization rotating unit #CMT#INORGANIC CHEMISTRY : #/CMT# The optically active material is a solid material, which is selected from neodymium-doped yttrium aluminum garnet, neodymium-doped gadolinium scandium aluminum garnet, neodymium-doped yttrium-gallium garnet, ytterbium-doped yttrium aluminum garnet, ytterbium-doped gadolinium scandium aluminum garnet, ytterbium-doped yttrium-gallium garnet, neodymium-doped gadolinium vanadate, neodymium-doped yttrium vanadate, ytterbium-doped gadolinium vanadate, ytterbium-doped yttrium vanadate, neodymium-doped potassium gadolinium tungstate, neodymium-doped sodium gadolinium tungstate, neodymium-doped potassium-lanthanum tungstate, ytterbium-doped potassium-gadolinium tungstate, ytterbium-doped sodium gadolinium tungstate, ytterbium-doped potassium-lanthanum tungstate or neodymium or erbium or ytterbium-doped crystals. |
