摘要

An integrated pulse shaper for femtosecond pulses was built and characterized. It uses far-field grating diffraction to generate the spectrum of an input pulse in the Fourier plane. The implementation of the system we present uses the concept of planar integration of free-space optical systems with a folded optical axis. The system is dispersion-free. Optical path-length differences are compensated for by using two cascaded 4f-imaging and filtering setups in the optical design. Material dispersion is avoided, since the light propagates in air and all optical elements in the system are implemented as reflective microoptical devices. Lenses were designed as concave mirrors and fabricated by ultraprecision micromachining. We present results regarding the design of the pulse shaper and its fabrication.
