FIBRE DUAL-FREQUENCY LASER WITH WAVE MIXING IN AMPLIFICATION OPTICAL FIBRES

摘要

The invention relates to a fibre dual-frequency laser having an optical source (1) emitting at least one main optical wave at a first wavelength (λ1), a fibre amplification medium (2), characterised in that it comprises means for interfering (11, 24, 201) with two primary optical waves (O1,O1') from the optical source in the amplification medium in order to create a diffraction array within said amplification medium, the first optical wave being diffracted into a second optical wave (O2, O2') having a second wavelength (λ2).
