The invention provides an active amplification type optical parameter oscillation feedback
system. The active amplification type optical parameter oscillation feedback
system comprises: a pumping source, an
optical coupling device, a non-linear
photonic crystal optical fiber, a light splitting device, an active
amplifier and an optical delaying device, wherein the pumping source is used for generating and outputting
laser; the
optical coupling device is used for
coupling laser output by the pumping source and
laser transmitted by the optical delaying device; the coupled laser is transmitted to the non-linear
photonic crystal optical fiber and then is processed; the processed laser is transmitted to the light splitting device to be split into two paths of light beams, wherein one path of
light beam is directly output and the other path of
light beam is transmitted to the active
amplifier; the active
amplifier is used for widening gains of a
laser light spectrum, and improving the
optical power of the laser; the laser is transmitted to the optical delaying device for delaying and the delayed laser is transmitted to the
optical coupling device again. According to the active amplification type optical parameter oscillation feedback
system, optical parameter oscillation feedback of the laser is realized, the
optical power of the laser of a
feedback loop can be improved and the gains of the
light spectrum are widened, so that the conversion efficiency of the optical parameter oscillation feedback is improved.
