Experimental investigation of high power picosecond 1.06 um pulse propagation in Bragg fibers

Popis výsledku v původním jazyce

In this paper we present fabrication and characterization of the laboratory-designed Bragg fiber. The fiber consisted of a silica core with the diameter of 26 ?m surrounded by 3 pairs of circular Bragg layers with a refractive index contrast up to 0.033.Spectral attenuation was measured using a halogen lamp source and the cut-back method resulting in the attenuation coefficient of 0.175 dB/m at 1064 nm. Experiments on high power laser radiation delivery were performed using a laboratory-designed passively mode-locked Nd:YAG laser system generating pulses with the duration of 20 ps and energy of 15 ?J at the wavelength of 1064 nm. The attenuation coefficient measurements resulted in a value of 0.168 ? 0.005 dB/m. The delivered beam spatial profile wasdetected in the far-field zone in the distance of ~1 cm from the fiber output face. The beam had a circular symmetry with almost Gaussian intensity profile. Bending losses were measured on 1-m long fiber segments using mandrels with diffe
