Abstract

We will present our proposal for a low-coherence laser facility - 'kunwu' - based on neodymium glass amplification of super-luminescent light pulse(SLP) with ~3.5 THz (13nm) bandwidth, and the beam has been converted to second harmonics before focusing on the target. We are validating the output capability of the laser (>10J/cm2@1ω) and improving the beam quality to achieve a more smoothing focal spot. We believe that this is a very ideal driving laser for laser inertial confinement fusion, and the scheme is very likely to be the best choice for the development of high-power laser drivers.
