A pumping module includes a solid state laser medium 3 having a light incidence surface 3 a which is bonded to a slab waveguide 2 and which accepts pumping light 1 propagating through the slab waveguide 2 , for absorbing the pumping light 1 introduced thereinto via the light incidence surface 3 a to amplify laser light, a total reflection film 4 for total-reflecting the laser light which emerges from an opposite surface 3 b of the solid state laser medium 3 , and an antireflection coating 7 for making the laser light total-reflected by the total reflection film 4 pass therethrough to output the laser light to outside the pumping module. As a result, the pumping module can output high-intensity high-power laser light.
