Solid-state laser system for color picture projection

The radiation emitted by a radiation source, such as a laser, is substantially prevented from exiting from the radiation source by a shutter in the radiation path. To make the shutter substantially fail-safe, two filter and/or diaphragm systems are switchable into the radiation path in series fashion in that one system is located behind the other system as viewed in the radiation direction. Sensors sense the effective or ineffective position of the respective system. Each system has an actuator for bringing the respective radiation stopping system into or out of the radiation stopping position in response to a control signal provided by the sensor of the respective other system.
