Title: Optical modulation device
Inventor: OMORI TAKEO
IPC: G02F1/11
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To perform intensity modulations with one optical modulation piece on the same incident condition in a 1st modulation and also in a 2nd modulation by intensity-modulating a laser beam at a prescribed ratio while converging it on an optical modulation element and converging the intensity-modulated laser beam on the optical modulation element again. SOLUTION: The laser beam 2 of a linearly polarized light emitted from a laser beam source 1 is made incident on a polarizing beam splitter 3. The laser beam transmitting the plane of polarization of the splitter 3 becomes a circularly polarized light via a quater-wave plate 4 to be made incident on a condenser lens 5. The laser beam made incident on the lens 5 is converged by its condensing action to form a beam waist at the focal position of a side opposite to the beam source of the condenser lens 5. Consequently, the laser beam is made incident on the acousto-optical element 6 positioned at the focal position opposite to the beam source of the condenser lens 5 in a state in which a beam diameter is smallest. Therefore, an intensity modulation is performed according to a prescribed extinction ratio with a prescribed high diffraction efficiency in the acoustic optical element 6.
