LASER OSCILLATION DEVICE, CAPABLE OF IMPLEMENTING CONTINUOUS WAVELENGTH VARIABLE LASING IN SEVERAL TENS NM OR SEVERAL HUNDREDS NM WAVELENGTH REGION

摘要

PURPOSE: A laser oscillation device is provided to manufacture wideband wavelength variable laser with the high efficiency by continuously generating a laser line in a monochromic wavelength in around 100nm or more range.;CONSTITUTION: A second substrate(120) is formed on the upper side of a first substrate(110). A wedge cell is formed between the first substrate and the second substrate. A liquid crystal layer(150) is formed by injecting two or more liquid crystals with different pitches into the wedge cell. The liquid crystals are dispersed in the wedge cell in order to form continuous pitch gradient. The liquid crystals are polymerized by the radiation of ultraviolet ray or heating.;COPYRIGHT KIPO 2011
