Abstract
To provide a laser ignition device in which the ignition efficiency is improved and the laser pulse energy necessary for ignition is minimized by optimizing the pulse time width of laser. The laser ignition device includes: a pulse laser oscillatorconfigured to output a beam having a wavelength λ [μm] and a beam quality M; an energy controllerconfigured to control energy of pulse laser outputted from the pulse laser oscillator; a lenshaving a focal length f [mm] and configured to focus the pulse laser outputted from the pulse laser oscillator; and a pulse time width controllerconfigured to control a time width of the pulse laser, wherein the pulse time width controllercontrols the time width of the pulse laser to be 0.6 to 2 ns.
