ELECTRONIC OPTICAL AMPLIFIER Russian patent published in 2009 - IPC H01S3/63 

FIELD: electricity.

SUBSTANCE: power increase is reached owing to introduction of electroluminescent converter, resonator lens, two turned reflecting mirrors and a turned semitransparent mirror. At that, optical output of light-emitting diode is connected to the first optical input of the turned semitransparent mirror having optical output connected through electroluminescent converter, through lens, through resonator to optical input of the first turned reflecting mirror, the optical output of which is connected to optical input of the second turned reflecting mirror having optical output connected to the second optical input of the above turned semitransparent mirror.

EFFECT: increasing power of reradiation without using massive assemblies.
