From: Intense multicycle THz pulse generation from laser-produced nanoplasmas
(a) Power of THz emission vs. colliding angles of the laser pulses. The power (including the contribution of non-beat-frequency components) is obtained by integrating THz intensity over y (from \(-32 \; \upmu \text {m}\) through \(+32\;\upmu \text {m}\)) passing through the probe lines at \(x=\pm 10 \; \upmu \text {m}\). (b) Power of THz emission with beat-frequency components only.
