      abstract = {This book advances understanding of light-induced phase  transitions and nonequilibrium orders that occur in a  broken-symmetry system. Upon excitation with an intense  laser pulse, materials can undergo a nonthermal transition  through pathways different from those in equilibrium. The  mechanism underlying these photoinduced phase transitions  has long been researched, but many details in this  ultrafast, non-adiabatic regime still remain to be  clarified. The work in this book reveals new insights into  this phenomena via investigation of photoinduced melting  and recovery of charge density waves (CDWs). Using several  time-resolved diffraction and spectroscopic techniques, the  author shows that the light-induced melting of a CDW is  characterized by dynamical slowing-down, while the  restoration of the symmetry-breaking order features two  distinct timescales: A fast recovery of the CDW amplitude  is followed by a slower re-establishment of phase  coherence, the latter of which is dictated by the presence  of topological defects in the CDW. Furthermore, after the  suppression of the original CDW by photoexcitation, a  different, competing CDW transiently emerges, illustrating  how a hidden order in equilibrium can be unleashed by a  laser pulse. These insights into CDW systems may be carried  over to other broken-symmetry states, such as  superconductivity and magnetic ordering, bringing us one  step closer towards manipulating phases of matter using a  laser pulse.},
