Modified femtosecond pulse shaper using microlens arrays

We discuss a modified femtosecond pulse shaper that uses microlens arrays to convert the continuous band of frequencies normally obtained in the mask plane of a pulse shaper into a series of discrete spots. Our experiments demonstrate that this modification can improve pulse-shaping quality when mod...

Description
Summary:We discuss a modified femtosecond pulse shaper that uses microlens arrays to convert the continuous band of frequencies normally obtained in the mask plane of a pulse shaper into a series of discrete spots. Our experiments demonstrate that this modification can improve pulse-shaping quality when modulator arrays with large interpixel gaps are used for Fourier-plane filtering.
