Abstract Upon femtosecond laser excitation in quantum materials, it is possible to study the many-body interactions through non-equilibrium processes, realize ultrafast electronic phase transitions, and achieve photoinduced novel states or hidden states. Such studies of interaction between materials are frontiers attract significant research interests field condensed matter physics. Time- angle-resolved photoemission spectroscopy a key experimental tool dynamics after photoexcitation. This paper reviews development high-resolution time- system based on nonlinear optical crystals using such setup, including (1) probing unoccupied (2) (3) new matter.
