Abstract
(EN)
A laser ignition device (1) is provided with an excitation light source (2) for generating excitation light, and a pulsed laser oscillator (4) connected to the excitation light source, wherein the pulsed laser oscillator generates a plurality of pulsed beams at the time of an ignition thereby producing an initial flame.
(FR)
L'invention concerne un dispositif d'allumage par laser (1) muni d'une source de lumière d'excitation (2) permettant de produire une lumière d'excitation, et d'un oscillateur laser pulsé (4) relié à la source de lumière d'excitation, l'oscillateur laser pulsé produisant une pluralité de faisceaux pulsés au moment d'un allumage, ce qui permet de produire une flamme initiale.
(JA)
このレーザ点火装置は、励起光を発生させる励起光源(2)と、前記励起光源に接続されたパルスレーザ発振器(4)とを備えるレーザ点火装置(1)であって、前記パルスレーザ発振器は、1回の点火時に複数のパルス光を発生させることで初期火炎を生成する。
