“…Accuracy of the phase front angular dispersion depends on the detector noise similarly as it was shown in the case of SSRI [57], since the phase extraction process is the very same in both cases. Experimental studies demonstrated 0.2 μrad/nm precision [53,106].…”

“…Cooled CCD can reach such signal-to-noise levels, where SSRI is capable to provide 0.02 fs can be considered typical values.

What We Can Learn about Ultrashort Pulses by Linear Optical Methods

Spatiotemporal compression of ultrashort pulses is one of the key issues of chirped pulse amplification (CPA), the most common method to achieve high intensity laser beams. Successful shaping of the temporal envelope and recombination of the spectral components of the broadband pulses need careful alignment of the stretcher-compressor stages. Pulse parameters are required to be measured at the target as well. Several diagnostic techniques have been developed so far for the characterization of ultrashort pulses. Some of these methods utilize nonlinear optical processes, while others based on purely linear optics, in most cases, combined with spectrally resolving device. The goal of this work is to provide a review on the capabilities and limitations of the latter category of the ultrafast diagnostical methods. We feel that the importance of these powerful, easy-to-align, high-precision techniques needs to be emphasized, since their use could gradually improve the efficiency of different CPA systems. We give a general description on the background of spectrally resolved linear interferometry and demonstrate various schematic experimental layouts for the detection of material dispersion, angular dispersion and carrier-envelope phase drift. Precision estimations and discussion of potential applications are also provided.

“…On the other hand, the SSI 23 is performed by crossing the signal and reference pulses in the image plane with zero delay to directly record the spectral amplitude and phase differences between them. Therefore, SSI is capable of a higher spectral resolution than SI and has been applied as a powerful method that can accurately measure the material dispersion, angular dispersion, and carrier-envelope phase drift 24,25 . In a version of SSI called Spatially Encoded Arrangement for Temporal Analysis by Dispersing a Pair Of Light E-fields (SEA TADPOLE) 26,27 , a Fourier transform-based algorithm is developed to facilitate the extraction of the field amplitude and phase of a pulse from the SSI interferogram.…”

We demonstrate that temporally-dependent polarization states of ultrashort laser pulses can be reconstructed in a single shot by use of an angle-multiplexed spatial-spectral interferometry. This is achieved by introducing two orthogonally polarized reference pulses and interfering them with an arbitrarily polarized ultrafast pulse under measurement. A unique calibration procedure is developed for this technique which facilitates the subsequent polarization state measurements. The accuracy of several reconstructed polarization states is verified by comparison with that obtained from an analytic model that predicts the polarization state on the basis of its method of production. Laser pulses with mJ-level energies were characterized via this technique, including a time-dependent polarization state that can be used for polarization-gating of high-harmonic generation for production of attosecond pulses.The common objective of ultrafast pulse characterization is to quantify the amplitude and phase of the electric field in spectral or, equivalently, in temporal domain. It may also be desirable or required to characterize the polarization state of the pulse 1 . It is well-known that the electric field associated with a laser pulse can be represented as a superposition of two component vectors that are orthogonally polarized. When an initially linearly polarized laser pulse propagates through a birefrigent dispersive medium such that its polarization is not parallel to one of the characteristic axes of the medium, its polarization can be converted into an elliptical state. In addition, the field envelopes of the two polarization components generally propagate at different group velocities in a birefringent media; consequently, a time-varying polarization state can be produced due to the temporal walk-off between them 2 . Arbitrary manipulation of polarization and temporal profile of a laser pulse can be accomplished by use of a Michelson interferometer, which can be referred to as the global polarization state generator 3 . In a Michelson interferometer, two orthogonal polarization components of an input pulse are split and propagated along two independent paths. Arbitrary amplitude and phase modulation can be independently applied to each polarization component by use of modulators placed into the two interferometer beam paths. Finally, the two components are combined at the output of the interferometer to synthesize an output pulse. In the contemporary implementations, polarization shaping of a laser pulse is realized by means of active methods, such as by placing a spatial-light modulator (SLM) containing an array of programmable liquid crystal (LC) cells [4][5][6] in the Fourier plane of a 4 f imaging system. By controlling the voltage applied to LC cells that introduce the spectral amplitude and phase modulation into their corresponding frequency components, polarization-shaped laser pulses with complex temporal variation throughout their pulse envelope can be produced.One major application of femtosecond (fs) lase...

The development of new optical materials and metamaterials has seen a natural progression toward both nanoscale geometries and dynamic performance. The development of these materials, such as optical metasurfaces which impart discrete, spatially dependent phase shifts on incident light, often benefits from the measurement of transmitted or reflected phase. Careful measurement of phase typically proves difficult to implement, due to high measurement sensitivity to practically unavoidable environmental sources of noise and drift. To date, no characterization technique has yet emerged as a frontrunner for these applications. This challenge is addressed using a custom‐designed three‐beam Mach–Zehnder interferometer capable of continuously referenced measurement of both phase and transmittance, resulting in a 10× reduction of noise and drift and phase measurement standard deviation over 10 min of 0.56° and over 16 h of 2.8°. High measurement stability provided by this method enables samples to be easily characterized under dynamic conditions. Temperature‐dependent measurements are demonstrated with phase‐change material vanadium dioxide (VO2), and with wavelength‐dependent measurements of a dielectric Huygens metasurface supporting a characteristic resonant reflection peak. A Fourier‐based signal filtering technique is applied, reducing measurement uncertainty to 0.13° and enabling discernment of monolayer thickness variations in 2D material MoS2.
