Dispersion compensation (pulse broadening/compression) using large chirped fiber Bragg grating is one of the key technologies in ultrafast laser field, which has become an important application direction of large chirped fiber Bragg grating. Raysung can customize CFBGS with various dispersion levels to meet the needs of ultrafast lasers.
Raysung’s ultrafast laser components can achieve high performance broadening, and achieve the ultimate in cost control. Can be customized according to customer requirements, meet the needs of high-performance picosecond laser femtosecond laser, to achieve the perfect unity of performance and cost.
It is specially designed for femtosecond pulse compression. In the CPA system of femtosecond fiber laser, VBG can be used to compress the broadened and enlarged pulse, which can achieve high quality ultra-short pulse compression
Providing various services like Metallization, Anti-reflection (AR) coating, Lensed fiber assembly and FBG+LENS Turn-key solutions.
The traditional small-chirped FBG is limited by its chirp coefficient, it has a small bandwidth and large dispersion rate, thus it cannot generally be used as a broadband filter device. However, the large chirped FBG has a wide bandwidth and a small amount of dispersion, it can be conveniently used in broadband filtering, amplifier noise suppression, gain flatness, fiber sensing and etc.
The application of CFBG in dispersion compensation has attracted more and more attention. The use of CFBG for dispersion compensation (pulse broadening/compression) is one of the core technologies in the field of ultrafast lasers, and has become an important application direction of large chirped FBG.
