    Abstract: Provided is a laser device including N semiconductor laser array stacks, a prismatic optical system that shifts optical axes of luminous fluxes respectively output from the N semiconductor laser array stacks so as to decrease intervals among the luminous fluxes, and an imaging optical system that causes the luminous fluxes to be condensed and deflected for each luminous flux. The imaging optical system causes the luminous fluxes to be deflected so that the luminous fluxes overlap each other at a predetermined position and generates a light-condensing point of the luminous fluxes between the imaging optical system and the predetermined position.

    Abstract: A laser apparatus includes a light source unit and a light combining unit. The light source unit outputs first laser light and second laser light having a wavelength different from that of the first laser light to different optical paths. The light combining unit is optically coupled to the light source unit, and combines the first laser light and the second laser light to generate a burst pulse with a frequency according to a difference between the wavelength of the first laser light and the wavelength of the second laser light. In the light source unit, the wavelengths of the first laser light and the second laser light are set in advance or settable such that the frequency of the burst pulse is 1 GHz or more.
