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.
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.
Raysung equips 30 work stations in its Fiber Bragg Grating (FBG) workshop, enabling a monthly production capacity of nearly 150,000 pieces. Raysung is capable of manufacturing various FBGs, including Uniform FBG, Apodized FBG, Double-Clad FBG, as well as Chirped FBG.
