Title:
半導体レーザモジュール
Document Type and Number:
Japanese Patent JP7461870
Kind Code:
B2
Abstract:
A semiconductor laser module that can increase output of an optical fiber laser is provided. The semiconductor laser module includes: a mounted-base member having a mounted-base face; a plurality of semiconductor laser elements installed on the mounted-base face of the mounted-base member; a lens that collimates laser light emitted from the semiconductor laser element; a condensing lens that condenses the laser light; and an optical fiber to which the condensed laser light is optically coupled, and further includes: between the condensing lens that condenses the laser light and the lens that collimates laser light emitted from the semiconductor laser element, an aperture that restricts light in a slow axis direction of the laser light.
