Axial scanning by pulse shaper for simultaneous spatial and temporal focusing of femtosecond laser pulses
نویسنده
چکیده
We develop a wide-field simultaneous spatial and temporal focusing (SSTF) setup for two-photon excited fluorescence microscopy and its axial focusing point is scanned by second-order dispersion added by a femtosecond laser pulse shaper placed before the setup. We measure the axial resolution of second harmonic generation (SHG) at the edge of a BBO crystal.

Parametric spatio-temporal control of focusing laser pulses.
Simultaneous spatial and temporal focusing pulses are created using parametric pulse shaping and characterized with scanning SEA TADPOLE. Multiple foci are created with optically-controlled longitudal and transverse spatial positions. The characterized foci are in agreement with the predictions of a Fourier optics model. The measurements reveal significant pulse front tilt resulting from the si...
متن کاملSpatio-temporally focused femtosecond laser pulses for nonreciprocal writing in optically transparent materials.
Simultaneous spatial and temporal focusing (SSTF) provides precise control of the pulse front tilt (PFT) necessary to achieve nonreciprocal writing in glass wherein the material modification depends on the sample scanning direction with respect to the PFT. The PFT may be adjusted over several orders of magnitude. Using SSTF nonreciprocal writing is observed for a large range of axial focal posi...
متن کاملCharacteristics and Applications of Spatiotemporally Focused Femtosecond Laser Pulses
Simultaneous spatial and temporal focusing (SSTF) of femtosecond laser pulses gives rise to strong suppression of nonlinear self-focusing during the propagation of the femtosecond laser beam. In this paper, we begin with an introduction of the principle of SSTF, followed by a review of our recent experimental results on the characterization and application of the spatiotemporally focused pulses...
متن کاملMultiphoton intrapulse interference. IV. Ultrashort laser pulse spectral phase characterization and compensation.
We introduce a noninterferometric single beam method to characterize and compensate the spectral phase of ultrashort femtosecond pulses accurately. The method uses a pulse shaper that scans calibrated phase functions to determine the unknown spectral phase of a pulse. The pulse shaper can then be used to synthesize arbitrary phase femtosecond pulses or it can introduce a compensating spectral p...
متن کاملFemtosecond optical packet generation by a direct space-to-time pulse shaper.
We demonstrate femtosecond operation of a direct space-to-time pulse shaper in which there is direct mapping (no Fourier transform) between the spatial position of the masking function and the temporal position in the output waveform. We use this apparatus to generate trains of 20 pulses as an ultrafast optical data packet over an approximately 40-ps temporal window.
