Title: Generation of ultrahigh speed, ultrashort flat-top picosecond electrical pulses by laser pulse shaping and ultrafast electro-optics sampling

Abstract

A novel method is proposed and demonstrated to generate ultrahigh speed, ultrashort flat-top picosecond electrical pulses by combining laser pulse shaping with ultrafast electro-optics sampling technique. Starting with high repetition rate laser pulses, a sequence of birefringent crystals is employed to produce optical pulses with flat-top temporal profile and tunable duration. Subsequent measurement of optical waveforms by an ultrafast photodetector yields high-speed, ultrashort flat-top picosecond electrical pulses. By using two sets of YVO4 crystals for laser pulse shaping, we report on the generation of 704 MHz, 48 picoseconds and 704 MHz, 88 picoseconds flat-top electrical pulses with 16-30 picoseconds rise or fall time. Lastly, to the best of our knowledge, these results are better than or comparable with the best performance using step recovery diodes and the direct electro-optics sampling technique.

An application of picosecond electro-optic sampling to superconducting electronics

Conference Dykaar, D R ; Hsiang, T Y ; Mourou, G A - IEEE Trans. Magn.; (United States)

A picosecond electro-optic sampling technique has been used to measure the switching threshold of a single tunnel junction in a coplanar transmission line geometry. The optical system used, a colliding-pulse mode-locked laser, generated two 120 fs FWHM at 100 MHz. One pulse was used, via a photoconductive switch, to generate an electrical signal of adjustable height and width. The second pulse was used to detect the electrical transient by probing the change in the birefringence of a lithium tantalate crystal induced by the electrical signal. This optical sampling scheme had intrinsic temporal and voltage resolutions of < 500 fs andmore »« less
Noncolinear Synthesis of Picosecond Flat-Top Laser Pulses to Increase Electron Photoinjector Brightness

Conference Lemons, R. ; Zhang, S. ; Neveu, N. ; ...

Next-generation electron photoinjector accelerators, such as the LCLS-II photoinjector, have increasingly tight requirements on the excitation lasers, often calling for tens of picosecond, temporally flat-top, ultraviolet (UV) pulse trains to be delivered at up to 1 MHz[1]. We present a numerical and experimental implementation of a non-colinear sum frequency generation scheme wherein the incident optical pulses have equal and opposite amounts of spectral dispersion resulting in a spectrally narrowband pulse with flat-top temporal profile[2]. In preliminary experiments we achieve upwards of 40% conversion efficiency with this process. We additionally demonstrate the ability for the narrowband pulses to be directly upconvertedmore » to the UV for driving a photocathode.« less

An ultrafast laser pulse picker technique for high-average-current high-brightness photoinjectors

Journal Article Zhao, Zhi ; Mernick, Kevin ; Costano, Michael ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

Beam diagnostics in high brightness photoinjectors requires that optical pulses from a high-power drive laser be picked up with an ultrahigh pulse contrast ratio and without temporal profile distortion. In high-average-current high-brightness photoinjectors, high-power drive lasers are routinely operated at GHz-level pulse repetition rate and it is challenging to achieve pulse picking without any pulse distortion. Here, we report on a new ultrafast pulse picker technique for beam diagnostics in high-average-current high-brightness photoinjectors. By efficiently combining an ultrafast low-power electro-optic modulator, high-power fiber laser amplifiers, a high-power Pockels Cell, and a frequency doubling module, we have successfully demonstrated optical bunchmore »« less

Generation of KrF laser pulses on a picosecond time scale using electro-optic modulation

Journal Article Curry, J J ; Feng, S T ; Goldhar, J - Opt. Lett.; (United States)

A new technique has been developed for the generation and shaping of KrF laser pulses on a picosecond time scale using a fast electro-optic modulator. Subnanosecond electrical pulses with an amplitude much greater than the half-wave voltage are applied to the Pockels cell, which generates a train of short ultraviolet pulses. The first pulse in this train is then isolated and shortened to 30 psec by the combined effect of propagation through a saturated amplifier and optical breakdown in xenon.

Pulsed-diode-pumped, all-solid-state, electro-optically controlled picosecond Nd:YAG lasers

Journal Article Gorbunkov, Mikhail V ; Shabalin, Yu V ; Konyashkin, A V ; ... - Quantum Electronics (Woodbury, N.Y.)

The results of the development of repetitively pulsed, diode-pumped, electro-optically controlled picosecond Nd:YAG lasers of two designs are presented. The first design uses the active-passive mode locking with electro-optical lasing control and semiconductor saturable absorber mirrors (SESAM). This design allows the generation of 15-50-ps pulses with an energy up to 0.5 mJ and a maximum pulse repetition rate of 100 Hz. The laser of the second design generates 30-ps pulses due to combination of positive and negative electro-optical feedback and the control of the electro-optical modulator by the photocurrent of high-speed semiconductor structures.
