Abstract
A dual frequency laser amplifier includes a beam generator for generating first and second source laser beams, and a co-doped optical fiber including first and second dopant ions having first and second gain bandwidths corresponding to the respective wavelengths of the first and second source laser beams for selectively forming first and second diffraction limited output laser beams responsive to the relative radiated power between the first and second source laser beams. A dual frequency laser oscillator and a method for generating the first and second output laser beams at any predetermined radiated power distribution are also described.
