【Abstract】 A propagating-guiding system for the high-power laser beam with a 51 meter opticalpath has been developed.A continuous wave laser beam with a beam power of an order of103 W can be propagated or guided by the system,with which the far-field divergency, far-field pattern, propagation in the atmosphere and the damage mechanism of the high-powerlaser beam can be investigated. The transmissive efficiency of the system is measured. Themain factors affecting the transmissive efficiency,including the reflectivity of the reflectivemirrors, absorption and scattering of the atmosphere and the diffraction loss, are discussed.The far-field patterns of the laser bearn guided by the system with a beam power up to 2 kWhave been measured.更多还原
