New white-light supercontinuum sources have no blue deficiency

Research output: Contribution to specialist publicationArticle


The invention of highly nonlinear photonic-crystal fibers(PCF's) and development of compact, high-power ultrafast fiber lasers enables white-light laser sources with 10 W and 10 mW/nm as powers and spectral power densities. The cause of blue deficiency in supercontinuum fiber lasers is result of output enhanced at blue wavelengths as technology is now being commercialized by Fianium. There is a demand of greater spectral bandwidth without loss in brightness or power and most commercial high-brightness supercontinuum lasers rely on ultrafast fiber laser operating at 1064 nm to pump the PCF's. The ESM fiber is not the optimal fiber design because the wavelength is between 450-500 nm. The results are visibly impressive, which is between 50 and 100 nm additional blue and UV spectral components are generated within the supercontinuum of new fiber design as compared to conventional and commercially available ESM nonlinear fibers.
