摘要 |
A laser device, includes: a fundamental wave generating portion configured to generate a plurality of fundamental waves having wavelengths which are different from each other in at least one set thereof, the fundamental wave generating portion having a semiconductor laser having a plurality of luminous points, and a Bragg reflection structure; and a nonlinear optical element in which a poling structure adapted to pseudophase matching for the wavelengths of the plurality of fundamental waves emitted from the fundamental wave generating portion, respectively, is formed variatively along a propagating direction of the plurality of fundamental waves.
