High-power optical fiber amplifier pumped with multimode laser source |
| abstract |
FIELD: optical fiber laser amplifiers. SUBSTANCE: amplifier is made of fiber 1 with two concentric cores 2 and 3; inner core 2 is amplifying medium and core 3 is used for pumping. Pumping radiation is transmitted from multimode source 4 and coupled crosswise relative to optical axis of fiber 1 with outer core 2 through multimode fiber 6 and multimode coupler 5. Pumping radiation is propagated over outer core 3 and is coupled with amplifying core 2 thereby pumping active medium. Composition of amplifying material is chosen so as to provide for pumping within comprehensive range of wavelengths. Both coherent and incoherent pumping sources may be used. EFFECT: improved power of optical fiber laser amplifier. 8 cl, 2 dwg |
