Ignition device for internal combustion engine, has laser-active solid body, quality switch, injection and decoupling mirrors of laser device formed as integrated monolithic part, and optical amplifier arranged in series with laser device
The device has a pump light source supplying a pump light. A laser device (26) generates a laser pulse signal that is emitted into a combustion chamber. An optical fiber device (28) transmits the pump light from the pump light source to the laser device. A laser-active solid body (44), a passive quality switch (46), an injection mirror (42) and a decoupling mirror (48) of the laser device are formed as an integrated monolithic part (50). The pump light is injected into an optical amplifier, which is optically arranged in series with the laser device.
