Fig. 2. (a) Extracted THz energy as a function of the second-order dispersion at 10 mJ pump energy. (b) Extracted THz energy and its corresponding optical-to-THz energy conversion efficiency for different pump energies at a chirped pulse duration of 187 fs.
Fig. 3. (a) Extracted THz energy and (b) the corresponding optical-to-THz conversion efficiency depending on pump energy.
Fig. 4. Optical-to-THz energy conversion efficiency as a function of pump energy at different optimization parameters.
Fig. 5. Extracted THz energy and its corresponding efficiency as a function of the pump energy. The TFP setup was optimized at a fixed pump parameter of 10 mJ pump energy with 187 fs pulse duration, and the iris before the compressor was slightly closed.
