Abstract ： We report here our recent studies of ultrastrong Langmuir tubulence by numerical simulation in two-fluid plasma. Many nonlinear phenomena, such as the formation and collapse of solitons, the onset of wavebreaking, the burnout and reborn of cavitons and so on, are observed in the simulation. Very intense cavitons ( |E|2 /2ε0 Te 3 and δn /n0 0.3 ) caused by relative weak pump ( (|E0 |2 /2ε0 Te 0.05 ) and fluctuations ( δn /n0 0.003 ) can exist in the system which are beyond the approximation of the Zakhorov model.
