PULSE FIBRE LASER WITH VARIABLE CONFIGURATION OF RING RESONATOR SUPPORTING RADIATION POLARISATION Russian patent published in 2015 - IPC H01S3/67 

FIELD: electricity.

SUBSTANCE: pulse fibre laser with variable configuration of ring resonator supporting radiation polarisation comprises a pumping source, a module of spectral convergence, which signal input is coupled to fibre insulator while its signal output is coupled to the active fibre, which is coupled to fibre brancher by its second end. The insulator and brancher are connected by their second ends to inputs of two fibre-optical switches operated as per 1×N scheme, where N is a number of outputs, at that under control by electronic signals each switch reswitches input optical signals to certain outputs, to which fibre-optical elements are connected thus ensuring active, passive or combined (active-passive) synchronisation of the laser radiating modes or Q-factor modulation of the laser resonator.

EFFECT: providing generation of pulses with different pulse length, energy and repletion rates within a wide band.
