摘要：
Nonlinear SRS and SBS restrictions for available peak power in single-mode fiber lasers were investigated. Various technical means to overcome the limitations were developed. As result, a feasibility of 100kW peak power at 5nsec pulse duration and 20W average power with near TEMoo output beam quality was demonstrated for ytterbium fiber laser with a MOPFA configuration. As alternative, Q-switch version of similar laser was developed using high-speed acousto-optic switch in ring geometry of fiber resonator. Temporal and spectral behavior of both versions vs peak power, pulse duration and repetition rate was investigated in details.
