The Nonlinear Effects on the Laser Pulses in Hollow Core Photonic Crystal Fiber

Abstract

In this paper we study the effect of nonlinear phenomena in hollow core photonic crystal fiber when a microseconds laser pulses from diode laser source with 675 nm wavelength and 1 KHz, 5 KHz and 10 KHz repetition rates propagate inside the fiber, the results showed that the spectral width of the pulse is broadening after passing the fiber due to the fiber nonlinearities
