Abstract
A laser includes a wavelength selecting elementthat selectively reflects laser beams with wavelengths λ=λ, λ, λ, . . . , λ(n≧1) of different laser oscillation modes from among fundamental oscillation wavelengths of laser beams passing through a wavelength conversion element, and the wavelength conversion elementthat converts the laser beams with the wavelengths λ=λ, λ, λ, . . . , λ(n≧1) of different laser oscillation modes reflected by the wavelength selecting elementto harmonics. When using a material with a wide gain band as a laser mediumof a solid-state laser element, a waveguide laser is implemented capable of carrying out high-efficiency wavelength conversion at a plurality of wavelengths within the gain band.
