Results of simulations and experiments on a high-power double-pass explosively pumped photo-dissociation iodine laser (EPDL) with phase conjugation (PC) are presented. The laser system consists of a master oscillator, two exploding amplifiers with a working mixture 25 Torr C₃F₇I+125 Torr Xe and amplifier aperture of 15 cm, and an SBS-mirror. The SBS mirror consists of an angular selector of Stokes radiation, an ordered raster of small diffraction lenses, a main focusing lens, and an SBS cell. The calculation model and the computer code package take into account the actual three-dimensionality of space, transient effects at SBS, parasitic reflections of laser radiation from elements of the optical scheme, intrinsic amplified spontaneous emission of amplifiers, radiation losses in the optical path, non-uniformity of gain, and radiation refraction on optical non-uniformities of the active medium caused by a shock wave. In the laser system, an optimal configuration of the SBS mirror is used. It possesses unique properties if compared to the existing specimens of SBS mirrors. It stably gives a nearly ideal quality of PC at any level of SBS saturation, i.e. any reflection coefficient that has been confirmed by experimental laboratory investigations. As a result of investigations, a good agreement of calculated results with available experimental data has been demonstrated in energy, time dependence of power and Strehl number of output radiation. The considered EPDL has output energy of about 400 J and brightness of about 10¹² J/sr. It has been found that with the increase of the flux density of an input signal from the master oscillator in the range 0.01-20 W/cm² the brightness of EPDL output radiation increases as well whereas the full energy varies relatively slightly. It has been shown that parasitic reflections of laser radiation from the ends of amplifiers and elements of the optical scheme with a coefficient exceeding 10^-7 considerably decrease the axial brightness of output radiation. In order to reduce the harmful effect of parasitic reflections on brightness the distance between amplifiers should be increased.

A non-steady-state theoretical and mathematical model and a complex of computer codes have been developed for modeling a high-power double-pass explosively pumped photo-dissociation iodine laser (EPDL) with phase conjugation (PC) at SBS. The model and the complex of codes taking into account 3D of space consist of two blocks. The first block is devoted to detailed modeling of the SBS mirror consisting of an angular selector of Stokes radiation, an ordered raster of small diffraction lenses, a main focusing lens, and a SBS cell. The second block describes the dynamics of radiation in the laser system as a whole with using SBS mirror parameters calculated in the first block. The model takes into account parasitic reflections of laser radiation from the elements of the optical scheme, intrinsic amplified spontaneous emission of the amplifiers, radiation losses in the optical path, non-uniformity of gain, and radiation refraction on optical non-uniformities of the active medium caused by a shock wave. As a result of calculations an optimal configuration of the SBS mirror has been determined, possessing unique properties if compared to the existing specimens of the SBS mirrors. It stably gives a nearly ideal quality of PC at any level of SBS saturation, i.e. any reflection coefficient that is confirmed by experimental laboratory investigations. Modeling of the laser sytem with two amplifiers at working mixture 25 Torr C₃F₇I+125 Torr Xe and amplifier aperture 15 cm has been shown a good agreement of calculated result with available experimental data in energy, time dependence of power and Strehl number of output radiation. The considered EPDL has output energy of about 400 J and brightness of about 1012 J/ster. Calculations show that under rising the density flux of input signal from the master oscillator in a range 0.01-20 W/cm², the brightness of the EPDL output radiation increase whereas the full energy varies relativley slightly. It is shown that parasitic reflections of laser radiation from the ends of amplifiers and elements of the optical scheme with a coefficient exceeding 10^-7 considerably decrease the axial brightness of output radiation. In order to reduce the harmful effect of parasitic reflections on brightness, the distance between the ampfiers should be increased.
