Abstract:
A high average power laser system with a scalable output power level, the laser system comprising:a master oscillator for generating pulsed light beams; one or more modular amplifier arms for providing an output light beam, each modular amplifier arm optically coupled to said master oscillator and including a power amplifier for amplifying said pulsed light beam distributed from said master oscillator and defining an output light beam; one or more first adaptive optics devices to provide precompensation of said light beam due to distortion of said power amplifiers, said first adaptive optics device being disposed upstream of said power amplifier in said modular arms; and a beam combiner for combining the output beams from said modular amplifier arms and providing a scalable composite output beam whose power level is a function of the number of modular amplifier arms connected to the system.
