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 laser materials processing industry requires high yields without sacrificing process stability to ensure high yield yields. As the output power increases, laser manufacturers face challenges such as thermal instability or nonlinearity that reduce the overall stability and reliability of the laser. Raysung's used in high power laser Raman scattering suppressor can eliminate the transmitting in the fiber laser laser signal of stimulated Raman scattering, the Raman scattering to reduce greatly help to improve the output of laser engine, at the same time improve its resistance to back light reflex, Raman scattering suppressor is allowed to use a smaller fiber core optical fiber laser manufacturers to reduce Thermal Mode Instability (TMI), thus improving pointing stability and spatial power distribution.
