Abstract
A device includes: at least one laser element with light emitting points to output fundamental waves in a one-dimensional array; a wavelength converting element to carry out wavelength conversion of the incident fundamental waves, and to output wavelength converted light rays; and an output mirror to reflect the fundamental waves, and to transmit the wavelength converted light rays resulting from the wavelength conversion by the wavelength converting element. The wavelength converting element is disposed between the laser element and the output mirror, and the distance between the position of a waist of the fundamental waves output from the laser element and the output mirror is set in accordance with a Talbot condition under which the adjacent light emitting points cause phase synchronization with each other.
