A new guide star laser using optimized injection mode-locking

Munch, Jesper; Rutten, Thomas P; Simakov, Nikita; Hamilton, Murray Wayne; d'Orgeville, Celine; Veitch, Peter John


We describe a new, improved approach for sodium guide-star lasers for the correction of atmospheric aberrations in telescopes, which satisfies all current requirements for advanced pulse burst waveforms. It makes use of sum frequency generation (SFG) of two pulsed, Q-switched, injection mode-locked Nd:YAG lasers, resulting in a macro-micro pulseburst output, optimized in power and bandwidth to maximize the fluorescence from the high altitude sodium layer. The approach is robust and power...[Show more]
