Laser ignition device for fuel air mixture, particularly internal combustion engine, has optically pumped laser medium, which emits pilot injection, coupled in fuel air mixture during operation

摘要

The laser ignition device has an optically pumped laser medium (6), which emits a pilot injection (7), coupled in the fuel-air mixture during an operation. The fuel-air mixture has a monolithic cascading multi-stage laser diode (3), which has an active area (30). The laser diode emits a number of pump beams (4), pumped by the laser medium. A profit-controlled laser structure is designed with the active area.
