Abstract
Provided is a device capable of oscillating a plurality of oscillation modes within a laser medium for obtaining a fundamental wave output which is easy in output scaling and high in luminance, thereby enabling a second harmonic conversion which is high in efficiency. The device includes: a laser medium () that is planar, has a waveguide structure in a thickness direction of a cross-section that is perpendicular to an optical axis (), and has a cyclic lens effect in a direction perpendicular to the optical axis () and the thickness direction; a clad () that is bonded onto one surface of the laser medium (); and heat sink () that is bonded onto one surface side of the laser medium () through the clad (), and in the device, a laser oscillation includes a laser oscillation that oscillates in a waveguide mode of the laser medium (), and a laser oscillation that oscillates in a plurality of resonator modes that are generated by a cyclic lens effect of the laser medium ().
