Laser device for ignition device of internal combustion engine of motor vehicle, has beam splitter arranged in beam path of laser pulses, where lateral part of cross-section of laser pulse strike surfaces of beam splitter

摘要

The device (26) has a beam splitter arranged in a beam path of laser pulses (24.1, 24.2) that are emitted by an optical resonator, where the beam splitter includes two inclined surfaces. A lateral part of a cross-section of the laser pulse strikes the surfaces of the beam splitter. A combustion chamber window is arranged in housing together with the optical resonator and the beam splitter. The beam splitter is designed as a prism with two prism surfaces. The chamber window is designed as a spherical lens, where the window and the splitter are made of quartz glass.
