Intense tunable terahertz radiation exceeding 500 GV/m is produced via phase-matched difference frequency generation in strongly magnetized plasmas by using two extraordinary-mode branches to minimize mismatch, validated analytically and with PIC simulations.
As the output frequency varies from 0.02ω0 to0.2ω 0, the indices of the three waves are all around 1 and have a maximum fluctuation about3%
