MODE CONTROL WAVEGUIDE LASER

摘要

There is provided a mode control waveguide laser capable oscillating a plurality of oscillation modes in a laser medium, so as to facilitate scaling of output obtain a high luminance basic wave output, and realize high efficiency second harmonic conversion. The mode control waveguide laser comprises a planar laser medium (5) having a waveguide structure in the thickness direction of a cross-section perpendicular to the optical axis (6) and exhibiting periodic lens effect in the direction perpendicular to the optical axis (6) and the thickness direction, a clad (4) bonded to one surface of the laser medium (5), and a heat sink (3) bonded to one surface of the laser medium (5) through the clad (4). Laser oscillation includes a laser oscillation in the waveguide mode of the laser medium (5), and a laser oscillation in a plurality of resonator modes formed by the periodic lens effect of the laser medium (5).
