    Optical-to-THz energy conversion efficiency as a function of pump energy at different optimization parameters.
    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.
