Abstract

We introduce a hybrid CPA system of Yb-doped fibers and Nd:glass rods, with use of aperiodic-frequency-converter crystal around 526 nm, demonstrated ~40% efficiency, and ~40 dB pulse contrast improvement. New result with novel SLT-made-AFC yielded ~60% efficiency, both showed near full bandwidth conversion. A Neodymium:glass CPA pulse yielded record energy result of 320s μJ in 527 nm second harmonic with the LiNBO3. Additionally, new, very low-cost, robust method, based on time-space nonlinear-index self-focusing effect showed >20-dB contrast enhancement.
