Device for Periodic Modulation of Laser Radiation

The device for periodic modulation of laser radiation comprises a modulating unit consisting of two disks, one of which is a fixed transparent disk, to the surface of which a phase diffraction grating is applied. The grating is located along the circumference at a distance Rg from the disk axis. The second disk has a diffraction grating identical to the fixed disk. The second disc is rotatable and coaxial with the fixed disc. Disks are located in parallel planes. The technical result consists in increasing the frequency of periodic modulation of the beam power. 1 drawing.
