چکیده
The technique of Optical parametric chirped pulse amplification (OPCPA) is becoming increasingly popular as pre-amplifiers for seeding laser systems [1,2] and as potential amplifiers for extremely high peak power systems. This is because they are capable of amplifying a broad bandwidth and can have large gains. Our previous study of the ASE contrast of the Vulcan laser system [3] demonstrated that the parametric fluorescence (PF) generated by the nanosecond OPCPA pre-amplifier acted to seed the rest of the amplification chain.

Multiterawatt few-cycle pulse OPCPA
A significant part of this work is devoted to the development of the brightest high-intensity few-cycle-pulse optical parametric chirped pulse amplifier (OPCPA) system. The completion of a 10 terawatt OPCPA is achieved, with 8.5-fs pulse duration at full-width at half maximum, which is within 6% of their Fourier transform-limited pulse duration. This was made possible by use of a combined grism...

194 LLE Review, Volume 99 Introduction Optical parametric chirped-pulse amplification1,2 (OPCPA) is well suited for the front end of modern petawatt glass laser chains.3 The broadband gain available with OPCPA at a wavelength of 1053 nm offsets the gain narrowing that occurs in large Nd-doped glass amplifiers.4 It can be scaled to large energies,5 in contrast to the practical limits imposed by ...
متن کاملIn vitro Gas Production and Dry Matter Digestibility of Irradiated Pomegranate (Punica granatum) Seeds
The objective of this study was to determine the effect of irradiation of pomegranate seed (PS) on chemical composition, digestibility and kinetic of gas production. Pomegranate seeds were exposed to gamma ray (GR) and electron beam (EB) at doses of 5, 10, 15 and 20 kGy. Three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...
متن کاملDesign of a highly stable, high-conversion-efficiency, optical parametric chirped-pulse amplification system with good beam quality.
An optical parametric chirped-pulse amplifier (OPCPA) design that provides 40% pump-to-signal conversion efficiency and over-500-mJ signal energy at 1054 nm for front-end injection into a Nd:glass amplifier chain is presented. This OPCPA system is currently being built as the prototype front end for the OMEGA EP (extended performance) laser system at the University of Rochester's Laboratory for...
متن کاملAn Investigation on Beach Profile Changes in Front of Seawalls
Although there exist advanced models which predict beach profile for natural beaches, the behavior of the beaches in front of seawalls still suffers from the lack of appropriate theoretical models and sufficient measured data. In this paper, following the results obtained from the measurements, a beach profile evolution model is developed, using the measured probability distribution of the nea...
