Mid-infrared chirped fiber Bragg gratings inscribed in fluorotellurite fiber using a femtosecond laser
{{output}}
In this paper, chirped fiber Bragg gratings (CFBGs) with tunable parameters are successfully fabricated in fluorotellurite fiber (FTF) using the femtosecond laser point-by-point method combined with slit beam shaping technique. By precisely controlling the pro... ...
