Abstract
The invention relates to a random optical fiber laser capable of achieving the output of cylindrical vector polarization laser. One end of the structure of the laser employs the rayleigh scattering of a long-distance single-mode passive optical fiber to provide random-distribution type feedback, thereby forming a resonant cavity along with a few-mode FBG (Fiber Bragg Grating) at the other end. Meanwhile, the structure employs the SRE (Stimulated Raman effect) of the single-mode passive optical fiber to provide gain, thereby guaranteeing that there is only a basic-mode laser oscillation in the resonant cavity of the laser. The laser wavelength is consistent with the working wavelength of the few-mode FBG. A fusing point of the single-mode passive optical fiber with a few-mode communication optical fiber employs a specific mode of fiber core staggering fusing, thereby achieving the high-order mode of effective excitation in the resonant cavity of the laser. Two polarization controllers are respectively disposed at two sides of the fiber core staggering fusing point, and the cylindrical vector polarization laser output with adjustable polarization can be obtained at an output end through the adjustment of the polarization controllers, i.e., obtaining radially polarized laser, angularly polarized laser, and laser in other polarization modes.
