Abstract
A laser beam generating apparatus includes a semiconductor element and a second harmonic generating element that performs a wavelength conversion on fundamental light emitted from the semiconductor element, the laser beam generating apparatus is an external resonance-type laser diode that has an external resonator structure and emits a transversal single mode laser beam, and the second harmonic generating element is a waveguide-type second harmonic generating element that includes a single mode waveguide.
