Sensitivity improvement of spectral phase interferometry for direct electric-field reconstruction for the characterization of low-intensity femtosecond pulses

A modified-SPIDER (spectral phase interferometry for direct electric-field reconstruction) technique where external powerful optical pulses are employed as a light source of chirped reference pulses for sum-frequency generation is proposed and is demonstrated experimentally. It provides great improvements in sensitivity and signal-to-noise ratio, and will enable a single-shot measurement for a ...

Spatio-temporal characterization of mid-infrared laser pulses with spatially encoded spectral shearing interferometry.

We report on the spatially resolved full amplitude and phase characterization of mid-infrared high intensity laser pulses generated in a three stage OPA. We use a spatially-encoded arrangement (SEA-)SPIDER with spectral filters for ancilla generation for spatially resolved characterization. Using five interchangeable filter sets we are able to characterize pulses from 1 to 2 μm with one single ...

Very narrow spectral filters with multilayered grating-waveguide structures

Promising configurations for grating-waveguide structures are presented. In these structures, the grating layer, which is normally adjacent to the waveguide layer, is displaced by means of an intermediate layer, resulting in significant reduction of losses and weaker coupling. This leads to very narrow spectral bandwidths and high contrast ratios. Experimental results reveal that the spectral b...

Self-Referenced Spectral Interferometry for Femtosecond Pulse Characterization

Since its introduction in 2010, self-referenced spectral interferometry (SRSI) has turned out to be an analytical, sensitive, accurate, and fast method for characterizing the temporal profile of femtosecond pulses. We review the underlying principle and the recent progress in the field of SRSI. We present our experimental work on this method, including the development of self-diffraction (SD) e...

Mid-infrared interferometry on spectral lines: I. Instrumentation

The Infrared Spatial Interferometer at University of California, Berkeley has been outÐtted with a Ðlter-bank system to allow interferometric observations of mid-infrared spectral lines with very high spectral resolution (j/*jD 105). This paper describes the design, implementation, and performance of the matched 32 channel Ðlter-bank modules, and new spectral-line observations of Mars and IRC ]...
