    摘要: A system and method for efficiently laser marking a polymer target material, and more particularly a transparent polymer target material, is presented. The system includes a visually transparent polymer target material comprising a surface and a near 2 μm fiber laser, the fiber laser having a peak power equal to or greater than 10 kW, a pulse repetition rate equal to or greater than 1 kHz, and an average power equal to or less than 20 W. In certain embodiments, the fiber laser may be a Q-switched fiber laser having a pulse width equal to or less than 200 ns or a mode-locked fiber laser having a pulse width equal to or less than 100 ps. The method includes producing, using the fiber laser, a mark that is not transparent to visible wavelengths on the surface of the polymer target material without damaging it.

    摘要: Method for fabricating of all-optical-fiber based optical polarizer devoid of fusing of first and second optical fibers. The method includes a process of forming a substantially adiabatic optical fiber taper by pulling an optical fiber and interrupting this process when an optical power parameter measured at an output of the optical fiber is reduced below a pre-defined threshold as a result of said pulling. An optically-tapered single-mode polarization-maintaining optical fiber element fabricated according to the method and configured as such all-optical-fiber polarizer.
