Abstract:
An analysis is made of the design of high-power laser systems comprising a master oscillator and a-series of amplifiers forming a pulse of the required shape. A method is developed for calculating the signal entering the amplifier series, which is necessary for obtaining the required pulse at the output. This method is applied to an 11-stage amplifying system with elements correcting the pulse shape. An original design of a system generating pulses of required shape and duration is described and the results of experimental tests carried out on this system are reported.
