Controlling laser light intensity, e.g. in video device to form image of video image with at least 3 laser beams, involves varying wavelength of light from laser source to vary output intensity

摘要

The method involves controlling the intensity of laser light (13) from a laser arrangement with a laser light source (1) and a non-linear optical element (6) arranged after the source in the light propagation direction by varying the wavelength of the light from the laser light source. The laser light source contains an oscillator (2) with a semiconducting laser AN Independent claim is also included for the following: (a) an intensity-controllable laser arrangement.
