Beschreibung
Zusammenfassung:	The device (27) has an ignition laser (26) with a laser-active solid body, and an outlet window for a laser beam (24). A pre-chamber is formed in housing, and is limited in sections by the outlet window and a replaceable insert. The pre-chamber includes a base plate on a side turned away from the ignition laser. An opening is formed in the base plate of the pre-chamber, and is arranged diagonal to a wall of the pre-chamber. Die vorliegende Erfindung betrifft eine Laserzündeinrichtung (27) für eine Brennkraftmaschine (10), insbesondere für einen Großgasmotor. Die Laserzündeinrichtung (27) umfasst einen Zündlaser (26) mit einem laseraktiven Festkörper (44), ein Austrittsfenster (58) für mindestens einen Laserstrahl (24) und ein Gehäuse (38). In dem Gehäuse (38) ist mindestens eine Vorkammer (63) ausgebildet und die mindestens eine Vorkammer (63) ist bereichsweise von dem Austrittsfenster (58) begrenzt.
