A laser light radiation device has a light source for emitting laser light which is modulated according to an image signal, a collimator lens for collimating the laser light emitted from the light source, and a polygonal mirror for deflecting the laser beam emerging from the collimator lens. The device further has a diffraction grating in a laser optical path between the collimator lens and the polygonal mirror.
