摘要： In a laser module in which laser beams emitted from semiconductor laser elements are collimated by collimator lenses, and condensed by an optical condensing system so that the laser beams converge at a light-entrance end face of an optical fiber. The semiconductor laser elements and the collimator lenses are contained in a hermetically sealed, first package which includes a front wall having a window arranged for passage of the laser beams, and a portion of the optical condensing system and the light-entrance end face are contained in a hermetically sealed, second package which is fixed to the front wall. The cross section of the second package perpendicular to the optical axis of the optical fiber at the light-entrance end face is smaller than the cross section of the first package parallel to the cross section of the second package.
