Abstract

A laser ignition device includes a laser oscillation optical system that produces pulsed laser light, a condensing optical element that condenses the pulsed laser light into a combustion chamber, a housing that internally contains the condensing optical element, and an optical window that is provided distally with respect to the condensing optical element in the housing and transmits the pulsed laser light. The pulsed laser light is shaped as a ring around an optical axis at least at a light passage position in the optical window.
