Measuring the spatiotemporal field of ultrashort Bessel-X pulses.

چکیده
We present direct measurements of the spatiotemporal electric field of an ultrashort Bessel-X pulse generated using a conical lens (axicon). These measurements were made using the linear-optical interferometric technique SEA TADPOLE, which has micrometer spatial resolution and femtosecond temporal resolution. From our measurements, both the superluminal velocity of the Bessel pulse and the propagation invariance of the central spot are apparent. We verified our measurements with simulations.

Measuring the spatiotemporal electric field of tightly focused ultrashort pulses with sub-micron spatial resolution.
We demonstrate a powerful and practical spectral interferometer with near-field scanning microscopy (NSOM) probes for measuring the spatiotemporal electric field of tightly focused ultrashort pulses with high spatial and spectral resolution. Our measurements involved numerical apertures as high as 0.44 and yielded the spatiotemporal field at and around the foci produced by two microscope object...
متن کاملDirect spatiotemporal measurements of accelerating ultrashort Bessel-type light bullets.
We measure the spatiotemporal field of ultrashort pulses with complex spatiotemporal profiles using the linear-optical, interferometric pulse-measurement technique SEA TADPOLE. Accelerating and decelerating ultrashort, localized, nonspreading Bessel-X wavepackets were generated from a approximately 27 fs duration Ti:Sapphire oscillator pulse using a combination of an axicon and a convex or conc...
متن کاملSpatiotemporal amplitude and phase retrieval of Bessel-X pulses using a Hartmann-Shack sensor.
We propose a new experimental technique, which allows for a complete characterization of ultrashort optical pulses both in space and in time. Combining the well-known Frequency-Resolved-Optical-Gating technique for the retrieval of the temporal profile of the pulse with a measurement of the near-field made with an Hartmann-Shack sensor, we are able to retrieve the spatiotemporal amplitude and p...
متن کاملNumerical simulations of holographic spatiospectral traces of spatiotemporally distorted ultrashort laser pulses.
We simulate traces for a catalog of spatiotemporally complex pulses measured using a single-shot complete spatiotemporal pulse-measurement technique we recently developed, called Spatially and Temporally Resolved Intensity and Phase Evaluation Device: Full Information from a Single Hologram (STRIPED FISH). The only such technique ever developed to our knowledge, STRIPED FISH measures the comple...
متن کاملEvidence of X-Shaped Propagation-Invariant Localized Light Waves
Ten years ago Durnin, Miceli, and Eberly [1] reported on the startling first experimental investigation of the socalled nondiffracting Bessel beam, which was formed from a cw laser light by an annular slit and a collimating lens. The beam was found to maintain its sharply peaked radial profile over large distances outclassing the Rayleigh range. During the decade monochromatic Bessel beams have...
