Abstract
A green laser optical module includes a pumping laser, a solid-state laser, and a second harmonic generator. The pumping laser generates excitation light. The solid-state laser is excited by the excitation light and generates first light in an infrared wavelength band. The second harmonic generator converts the first light into second light in a green wavelength band and includes at least two polarization converting regions.
