All-optical three-dimensional electron pulse compression [PDF]

open access: yesNew Journal of Physics, 2015
We propose an all-optical, three-dimensional electron pulse compression scheme in which Hermite–Gaussian optical modes are used to fashion a three-dimensional optical trap in the electron pulse’s rest frame.

A computationally efficient pulse compression method of Barker-coded excitation using a mismatched filter in medical ultrasound imaging [PDF]

open access: yesUltrasonography
Purpose Barker-coded excitation, which is well suited for portable ultrasound imaging because it preserves frame rate and uses binary encoding, exhibits a high range sidelobe level of 1/N after pulse compression.

Design of Self-similar Pulse Compression Grating Pair based on Chirp Compensation

open access: yesGuangtongxin yanjiu, 2021
In order to obtain a high-quality ultrashort pulse light source, we combine the self-similar pulse with the grating pair, and analyze the evolution and compression process of the self-similar pulse in detail through a numerical simulation method.

High-energy few-cycle pulses: post-compression techniques

open access: yesAdvances in Physics: X, 2021
Contemporary ultrafast science requires reliable sources of high-energy few-cycle light pulses. Currently two methods are capable of generating such pulses: post compression of short laser pulses and optical parametric chirped-pulse amplification (OPCPA).
