Paper Abstract
Coupled unstable resonators and phase-matched amplifiers with a master oscillator (MOPA) are studied in the framework of coherent beam combination. Coherent combination is accomplished on multiline CW HF lasers by both approaches. It is shown that the MOPA approach requires a master oscillator with good beam quality in order to diagnose the mutual coherence of the two amplified beams and to demonstrate the narrowing of the far-field central lobe. The coupled-unstable-resonators approach is found to be more difficult due to the coupling-path alignment requirement. Attention is focused on a procedure for equalizing external paths for optimum far-field brightness of multiline phased arrays.
