摘要： An external-cavity laser light source apparatus includes a plurality of laser light emission modules, each including a first mirror, a second mirror reflecting fundamental wave light toward the first mirror, a lasing medium emitting the fundamental wave light, a wavelength converter performing wavelength conversion on incident fundamental wave light to produce first converted light and non-converted light. A third mirror reflects second converted light to produce reflected, converted light, the second converted light being wavelength-converted light produced when the non-converted light is reflected off the second mirror and incident again on the wavelength converter. The plurality of modules are disposed so that the first converted light beams exit the modules in the same direction and the reflected, converted light beams exiting the modules approach each other. A deflector may deflect the reflected, converted light beams exiting from the modules in the same exit direction as the first converted light.
