Abstract

A novel technique for simultaneous pulse reshaping and repetition-rate multiplication of mode-locked laser pulse trains using linearly chirped apodized fiber Bragg gratings is proposed. Simple analytical expressions for apodization and phase profiles of the grating are derived. The practical feasibility of this technique is discussed in detail for the case of high-repetition-rate square pulse generation and multiplication.
