Abstract
A waveguide is constructed by sandwiching a transparent member () and a laser medium () between a first clad-and a second clad-. Pumping light () is made to be incident from a direction perpendicular to a direction of the optical axes of first to fourth laser oscillation light beams-to-, and to alternately propagate through the transparent member () and the laser medium () in a zigzag manner so as to pump only resonator mode regions in the laser medium ().
