Supercontinuum generation in the irregular point of hollow-core photonic crystal fiber.

Broadband supercontinuums (SC) are generated by soliton self-frequency shift (SSFS) of hollow-core photonic crystal fiber (HC-PCF) in our laboratory. With the pump works at 810nm when the pump power increase from 400 to 600mW, the Raman Soliton shifts from 2089 to 2215nm, the bandwidth of SC increases from 2213 to 2320nm. The ultra-violet part of SC is below 180nm, and the mid-infrared part of SC exceeds 2500nm. Moreover, the influence of pump power on SC is also analyzed. [ABSTRACT FROM AUTHOR]
