Laserati

Yunqi Liu, Kin Seng Chiang
We demonstrate experimentally that the efficiency of writing a long-period fiber grating in a single-mode fiber by CO_2 laser pulses increases significantly with the axial stress applied along the fiber. We attribute the enhancement in writing efficiency to the generation of nonuniform inelastic ... [Opt. Lett. 33, 1933-1935 (2008)]
