摘要： In a laser module, a laser beam which is emitted from a laser element is focused by a condensing optical system and caused to enter an incidence end of an optical fiber. A laser device is provided with a plurality of these laser modules. Emission end portions of the optical fibers are bundled to form a laser emission portion. A thickness of cladding h of each optical fiber is set to a value calculated in accordance with the following equation: cladding thickness ⁢ ⁢ h ≤ ( emission ⁢ ⁢ light ⁢ ⁢ amount of ⁢ ⁢ one ⁢ ⁢ laser ⁢ ⁢ module ⁢ ⁢ W required intensity ⁢ ⁢ C × packing ratio ⁢ ⁢ P - core diameter ⁢ ⁢ t ) ÷ 2 As a result, it is possible to emit a laser-beam with a high intensity that is required for functionality as a laser light source, for the purpose of raising resolution of an exposure apparatus.
