Abstract
We present an approach for green laser-light generation based on a fiber superluminescent pulse amplification system and frequency doubling to 552 nm with a periodically poled lithium niobate (PPLN) crystal. The SPA system used in the experiment is capable of yielding 6-nm-bandwidth, 10 ns pulsees. The 10-mm-long PPLN with 6.95 μm period and 0.5 mm thick generated high-power green light with single pulse energy up to 5.49 μJ when hte broadband input pulse coherence characteristics of the superluminescent pulse amplifier and the frequency doubling. This generated green light has proved to have low speckle noise and low photon degeneracy.
