Abstract
The invention discloses a photonic crystal fiber based medium-infrared optical fiber parametric oscillator for degenerating four-wave mixing and relates to a laser oscillator. The photonic crystal fiber based medium-infrared optical fiber parametric oscillator is provided with a laser pumping source, a focusing lens system, four reflectors and a photonic crystal fiber which are sequentially serially connected to an optical fiber annular cavity, the laser pumping source is coupled to enter the photonic crystal fiber through the focusing lens system, oscillation and lasing of signal light in a visible light wave band are guaranteed by the four reflectors, and coherent medium-infrared idle-frequency light is outputted from the tail end of the photonic crystal fiber. Pumping laser with the wave range of 1030-1070nm is coupled to the photonic crystal fiber to stimulate nonlinear effect of the optical fiber four-wave mixing so as to achieve output of the laser in the medium-infrared wave band. The four reflectors in a resonant cavity structure of the oscillator are used to guarantee that the signal light in the visible light wave band is completely reflected in the cavity, and coherent medium-infrared idle-frequency light is completely outputted from the tail end of the photonic crystal fiber so that conversion efficiency is high.
Description
technical field [0001] The invention relates to a laser oscillator, in particular to a mid-infrared optical fiber parametric oscillator based on photonic crystal optical fiber degenerate four-wave frequency mixing. Background technique [0002] Mid-infrared laser sources have important application value and prospects in both military and civilian applications. There are many technical approaches to realize mid-infrared lasers, which can be mainly divided into four categories, namely: (I) semiconductor quantum cascade lasers ([1] P.Q.Liu, A.J.Hoffman, M.D.Escarra, K.J.Franz, J.B.Khurgin, Y. Dikmelik, X.Wang, J.-Y.Fan, and C.F.Gmachl, "Highly power-efficient quantum cascade lasers", Nat. Photon., vol.4(2), pp.95-98, 2010); (II ) Rare earth crystal laser ([2] K.S.Lai, W.J.Xie, R.F.Wu, Y.L.Lim, E.Lau, L.Chia, and P.B.Phua,"A 150W 2-micron diode-pumped Tm:YAG laser,"in Proceedings on Advanced Solid-State Lasers (OSA), vol.68, pp.535-539, 2002, Washington); (III) Solid-state cry...
