FIELD: physics.
SUBSTANCE: invention can be used for recording of pulse shape of optical radiation and measuring of its power, and also for reception single or series of ultrashort electrical impulses. Photodetector consists of substrate, nanographite film executed from graphite nanocrystals which base planes are canted to the surface of substrate and are preferentially undirectional, and two parallel electrodes having electrical link with it. The electrodes can be located parallelly preferred direction of edges of dihedral angles formed by plane of substrate and base planes of crystal grains.
EFFECT: increase of operational performances of device.
