The research on studying and development of iodine lasers for experiments in the field of ICF, conducted in RFNC- VNIIEF, were resulted in the creation of 120 TWt 12-channel pulse iodine laser facility 'Iskra-5'. Wavelength of radiation is (lambda) equals 1.315 micrometers . 'Iskra-5' installation is designed on the scheme of parallel amplification of pulse, generated by front-end system, in 12 identical amplifying channels. Front-end system includes four main parts: master oscillator (MO), two cascades of preliminary amplification (PA1, PA2) and final amplifier (A0). Radiation from front-end system after A0 passes through the splitting system to the input of amplifying channels. Topics of report are short description of 'Iskra-5' front-end system and analysis of its parameters during previous five years of facility operation. Modernization of master oscillator is reported also. This modernization includes changing of electro-optical mode-locker on acousto-optically mode-locker made from crystalline quartz. Using of crystalline quartz allowed to get 100% depth of modulation on the wavelength of iodine laser radiation under control power about 10 Wt. The analysis of results revealed that using of acousto-optical modulator significantly stabilizes the parameters of front- end system radiation pulse.
