N2 - A novel femtosecond inscription technique based on spatial light modulator has been developed to enable focal spot scanning within the static focal spot that opens the way for fabricating refractive index structures with arbitrary complex cross-section geometry including line-by-line and ring-shaped broadband reflectors with random periods and thus enhanced Rayleigh backscattering (RB). The influence of inscription parameters (pulse energy, objective NA, reflector length) on refractive index modulation amplitude, RB level enhancement and reflectivity was demonstrated. Moreover, SLM-inscribed artificial Rayleigh reflectors were used to enhance random distributed feedback strength in narrow-linewidth Er3+-doped fiber laser, as well as to select higher-order transverse mode in the output beam at the low generation threshold of down to 120 W of random Raman lasing in multimode fiber, while broadband reflectivity offers laser wavelength tunability potential.
