Paper Abstract

Femtosecond pulse shapers are an important tool for the manipulation of ultrashort pulses. Two-Liquid-Crystal (LC)- Panel Spatial Light Modulator (SLM) pulse shapers5 are especially useful, as they permit simultaneous control of phase and amplitude of spectral components, thereby allowing for a wide range of possible manipulations of the temporal shape of ultrashort pulses. In this work, a detailed description of the alignment of a pulse shaper optimized for modelocked semiconductor lasers is presented. Several methods to calibrate the phase-retardance-LC-voltagerelationship are reviewed and a calibration method is presented which is robust to non-idealities of the components of the setup.
