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.

LED light source

The invention pertains to electronics and energy-saving technologies, more specifically to the construction of LEDs. The LED light source comprises film semiconductor layers deposited on a conductive substrate serving as one of the electrodes having a polycrystalline structure with p-n junctions in many grains of a polycrystalline film and coated externally with a layer of transparent conductive material serving as a second electrode. The invention provides the possibility of creating a light source that is more durable, with a larger integral light flux and a cheaper one.
