光モニタ装置。In a laser beam monitoring device using an optical shutter or the like, the optical shutter or the like includes a set of polarizers 3.4 through which the incident light 1 passes, and these polarizers 3,
A Pockels self that rotates the polarization plane of the laser beam by 90 degrees by applying a high voltage to the laser beam that has passed through the Pockels self, and a set of polarizers 5.6 that allows the laser beam that has passed through the Pockels self to pass through and partially reflects it. , further includes an incident light detector 9 that detects the reflected light partially reflected from the polarizer 6, and a reflected light 2 that is the laser light emitted to the outside from the - pair of polarizers 5.6 and reflected by a target or the like. A reflected light detector 10 detects the reflected light that is almost reflected by the polarizer 4 after passing through the - pair of polarizers 5.6 and the Pockels self, which does not rotate the plane of polarization because no high voltage is applied. A laser beam monitoring device comprising:
