The effect of laser wavelength on laser-plasma coupling is one of the critical issues facing the laser driven inertial confinement fusion community. Advantages of using lasers with output wavelength of <1µm, such as enhanced absorption and hydrodynamic efficiency, reduction in parametric instabilities, and corresponding suprathermal electron generation, have long been predicted theoretically. However, the details of and competition between the important processes occurring in the laser plasma interaction are not known well, and thus quantitative scaling with the driver wavelength is extremely uncertain.
