Method for stabilising the output power of a solid-state laser, and a solid-state laser system

摘要

A method for stabilizing the output power of a solid state laser with resonator internal frequency multiplication, in which at least two components of the of the solid state laser output radiation is measured and for controlling the output power of the solid state laser to a constant value at least one variable,characterized by the,that for the controlling of the output power of the solid state laser is influenced at least one second correcting variable, wherein for each manipulated variable is determined in each case a separate input value, andthat the control bandwidth of the two correcting variables comparable with the characteristic frequencies of the fluctuation of the intensity of the solid state laser is.
