Paper Abstract

The present paper analyzes different methods for dynamic control of parameters of super-continuum generated in fibres both under pulse and CW pumping as well as peculiarities of temporal structure of different super-continua. In particular we show experimentally and numerically a sensitivity of supercontinuum spectral power density to wavelength and repetition rate of pump pulses. We find also that chirp variation of pump pulses results in change of super-continuum coherence for short-wavelength wing. A novel method for control of SC generation under CW pumping is proposed. We discuss the method for control of repetition rate and duration of pulses generated with the help of dual-wavelength pumping by means of adjusting input power and frequency difference. Developed super-continuum generators with enhanced set of controlled parameters are essential for cytometry, tomography, spectroscopy, communications and for other applications.
