The parameters of a two-channel five-zone rectangular dielectric structure are presented in order to experimentally test the obtaining of high transformation ratio when using such structures for wakefield acceleration. The report also investigates the permissible deviations of the structure parameters that affect the value of the transformation ratio and the acceleration gradient. A model of five-zone rectangular dielectric structure based on a metal waveguide R15 was manufactered. A calorimeter was made to measure the energy of the wakefield excited in the dielectric structure by electronic bunches. The schematic diagram of the CPA of the laser installation in the case of integration of Nd-YAG pumping laser with high output energy, which includes optical circuits of the Low Optical Signal Amplifier (LOSA) and Power Amplifier. The scheme provides a branch of 40 mJ of Nd-YAG laser radiation at a wavelength of 532 nm to pump the LOSA and more than 200 mJ  to pump the Power Amplifier. Based on the presented scheme, a Nd-YAG high-energy pumping unit integrated and integrated into a CPA laser unit was developed and created. The choice of the optimal version of the compressor with one diffraction grating and "roof" reflectors is substantiated. An example of the results of the calculation of the compressor with one diffraction grating and reflectors of the "roof" type for the case of its application in the CPA in a laser installation with an output power ≤5 TW Product Description popup.authors Vasyliev Andrii Vadimovich Zalesky Dmitro Yurievich Povrozin Anatoliy Ivanovich Prystupa Valeriy Ivanovich Sotnikov Genadiy Vasylyovych popup.nrat_date 2022-03-09 Close
