A semiconductive laser module according to the present invention is configured with a semiconductive laser module having a semiconductive laser device, a cavity formed with at least one light feedback means included, and an optical fiber located at a front side of the cavity, wherein an optical filter for transmitting light of wavelength within a predetermined range is disposed in the cavity. The above-noted semiconductive laser module additionally has a combination of a collimator and a focusing lens for coupling emitted light from the semiconductive laser device with the optical fiber, and the optical filter is disposed between the collimator and the focusing lens. The optical filter has a dielectric multi- layered filter for transmitting a desired wavelength. A laser unit according to the present invention is configured with a plurality of semiconductive laser modules as noted above, and a polarization combiner for making a polarization combination of emitted light from the plurality of semiconductive laser modules. A Raman amplifier according to the present invention has a pumping light source configured with the semiconductive laser module or the laser unit.
