ARRAY TYPE WAVELENGTH CONVERTING LASER DEVICE

摘要

An array type wavelength converting laser device is provided with: a single or a plurality of laser elements (1) that have a light emitting point and output fundamental waves in a one-dimensional array form; a wavelength conversion element (2) for carrying out wavelength conversion of incident fundamental waves and outputting wavelength converted light; and an output mirror (3) for reflecting the fundamental waves and allowing the wavelength converted light for which the wavelength has been converted by the wavelength conversion element (2) to pass through. The wavelength conversion element (2) is disposed between the laser element (1) and the output mirror (3), and the distance between the position of the waist (103) of the fundamental waves output by the laser element (1) and the output mirror (3) is set by Talbot conditions that generate phase synchronization among neighboring light-emitting points.
