We describe the design, performance, and characterization of our laser system, which has the potential for achieving a peak power of 600 TW. We also describe applications of the laser system in the relativistically dominant regime of laser-matter interactions and discuss a compact, high efficiency diode-pumped laser system. %K ultra-intense laser %K chirped-pulse amplification %K Ti:sapphire laser %K high field science %U http://www.mdpi.com/2076-3417/3/1/214
