We present some specific high power laser systems that are being developed at our laboratory for many applications such as high field science and nonlinear optics. We report on an ultra-high intensity petawatt-class OPCPA/Ti:sapphire hybrid laser system that can produce a pulse energy of ~18 J with ~30 fs pulse duration for studying extremely high intensity laser matter interaction processes, a small-scaled OPCPA/Yb:YAG hybrid laser system that can generate a pulse energy of ~100 m J with ~500 fs pulse duration at 10 Hz as a compact and high efficiency system, and a Nd:YAG master oscillator power amplifier (MOPA) laser system that can provide a pulse energy of 360 mJ with 30 ns pulse duration at 1 kHz as a high average power laser system. We also briefly introduce a Yb:YAG laser system that is being constructed to realize a pulse energy of 100 mJ of ps pulse duration at 1 kHz as a high repetition system and an OPCPA laser that is being developed toward a pulse energy of 10 mJ of sub-10 fs pulse duration at 1 kHz as an ultra-short pulse and high repetition laser system. We discuss the basic design aspects and present the results from our experimental investigations of these laser systems.
