When a laser light source module includes a heat sink in which a solid laser element, an excitation light source, and a wavelength conversion element are arranged and a stem that supports the heat sink, wherein the heat sink is separated into three blocks, namely a first block including a laser oscillating unit for the solid laser element is arranged, a second block including a semiconductor laser element that emits excitation light for the laser oscillating unit and a first temperature sensor are arranged and on a specific surface of which the first heater is arranged, and a third block including the wavelength conversion element that converts the wavelength of the fundamental laser beam and a second temperature sensor are arranged and on a specific surface of which a second heater is arranged, enabling thus downsizing of the module and improvement of the positioning accuracy of the elements.
A laser light source module comprising a heat sink in which a solid laser element that oscillates a fundamental laser beam, an excitation light source that excites the solid laser element, and a wavelength conversion element that converts a wavelength of the fundamental laser beam oscillated by the solid laser element, and a stem that supports the heat sink, wherein:
