200TW peak power at 45 fs pulse duration (910 nm central wavelength) has been achieved experimentally using three optical parametrical amplifiers based on KD*P crystals. Energy conversion efficiency… (More)
A theoretical model of second-harmonic generation (SHG) under strong influence of cubic nonlinearity was verified in experiment. Effective energy conversion in thin potassium dihydrogen phosphate… (More)
A chirp pulse at 910 nm was amplified from 1 nJ to 100 mJ by an optical parametric amplifier Computations show that adding two more parametric amplifiers (100 mm and 300 mm diameter) will result in a… (More)
Visualization of growth-sector boundary and point defects in non-linear optic crystal (KDP) was performed by phase-contrast method with adaptive photothermal Zernike filter.
In spite of the fact that the petawatt level has been attained quite a time ago [ 1 ], only a few petawatt facilities are available worldwide. One of them, a 056 PW OPCPA facility, was created at the… (More)
Numerical simulation of the process of inversion of the small-scale image of the object in phase-contrast scheme with nonlinear Kerr filter described.
This paper presents a 0.5-PW 45-fs laser system based on optical parametric chirped pulse amplification (OPCPA). The 0.56 PW peak power has been achieved experimentally using an upgraded setup. The… (More)
Method for obtaining an inverted brightness image of opaque objects is described. Obtained transformation to a positive image up to 350%, relative to the intensity of the incident beam, is in… (More)
The use of photothermal Zernike phase-contrast filter for measuring the absorption of the medium proposed. Results of numerical simulation are given. It is shown that the efficiency is comparable to… (More)
Experiments on electron and ion acceleration using powerful laser radiation have been successfully carried out lately. A possibility to get high electron energies amounting hundreds of MeV and even… (More)
