Ultrashort Pulse Generation from High Power Diode Arrays using Intracavity Nonlinearities

Abstract

The development of high power semiconductor diode laser arrays and broad area devices makes possible the use of new mode-locking techniques which utilize high intracavity intensities to produce nonlinearities. Short pulse generation may be investigated and optimized using hybrid cavity designs which incorporate a controlled amount of self phase modulation (SPM), group velocity dispersion (GVD), and fast saturable absorption.
