OPTOELECTRONIC AMPLIFIER Russian patent published in 2013 - IPC H01S3/10 

FIELD: physics.

SUBSTANCE: optoelectronic amplifier has a turned semitransparent mirror, two turned reflecting mirrors, a radiation source, two optoelectronic converters and two correcting lenses. The optical output of the first correcting lens is connected through a first optoelectronic converter to the optical input of the second correcting lens. The device includes a second amplifier, a third correcting lens and a third turned reflecting mirror, having an optical input and an optical output respectively connected through the second turned reflecting mirror, through the third correcting lens to the optical output of the second correcting lens and through the first turned reflecting mirror to the first optical input of the turned semitransparent mirror. The first optical output, second optical input and second optical output of the turned semitransparent mirror are respectively connected to the optical input of the first correcting lens, the optical output of the radiation source and the optical input of the second amplifier.

EFFECT: high light amplification.
