ABSTRACT:
A laser source device includes: a light emission unit which emits laser beam having first wavelength; a first mirror which selectively reflects S-polarized light contained in the first wavelength laser beam emitted from the light emission unit in a direction different from the direction toward the light emission unit and transmits second wavelength laser beam; a second mirror which receives laser beam reflected by the first mirror and reflects laser beam having first wavelength and contained in the received laser beam toward the first mirror; and a wavelength conversion element disposed between the first mirror and the second mirror and converts at least a part of S-polarized light contained in the received first wavelength laser beam into laser beam having second wavelength.
