Abstract

Supercontinuum generated in optical fibers due to various nonlinear processes has a very broad spectrum and it is one of the most important and analyzed nonlinear optics phenomena, which has many important applications. Although a wide variety of supercontinuum generation in PCFs research has been done, research in which the length of a short PCF is changed in small steps has not been performed. Since extremely rapid spectrum extension in femtosecond regime of supercontinuum generation occurs in the first few centimeters of the PCF, comprehensive knowledge of spectrum evolution is necessary to improve efficiency of this nonlinear processes. In this paper we present our experimental of light generation in short PCF, when fiber length was changed in small steps using ~ 110 fs duration and 1030 nm wavelength pulses pumping.
