    Data associated with the manuscript 'Efficient and stable second harmonic conversion, at the 0.5 kW-level, of a diode-pumped Yb:YAG laser'
    (2023-10) Clarke, Danielle
    This dataset contains the experimental data presented in the manuscript 'Efficient and stable second harmonic conversion, at the 0.5 kW-level, of a diode-pumped Yb:YAG laser'. In the manuscript, efficient and stable, type-I phase matched second harmonic conversion of a nanosecond high-energy, diode-pumped, Yb:YAG laser is presented. With the frequency doubling crystal in an enclosed, temperature-controlled holder with optical windows, an RMS energy stability of 0.49 % was achieved for a period of approximately half an hour. This resulted in 48.9 J pulses at 10 Hz (489 W) and a conversion efficiency of 73.8 %. The dataset includes data for a range of set-point temperatures (30, 40, 50 and 70 dgerees) for the two temperature-controlled (TC) holders, TC1 and TC2. 'HJ-D-P4-EM-1' is the input energy at 1030 nm. 'HJ-SHG-1W' is the residual 1030 nm energy after the frequency doubling crystal. 'HJ-SHG-2W' is the converted 515 nm energy after the frequency doubling crystal.

    Data associated with the manuscript titled “Towards terawatt-scale spectrally-tunable terahertz pulses via relativistic laser-foil interactions”
    (2020-07) Liao, Guoqian; Liu, Hao; Scott, Graeme; Zhang, Yihang; Zhu, Bao-Jun; Zhang, Zhe; Li, Yutong; Armstrong, C. D.; Zemaityte, Egle; Bradford, Philip; Rusby, Dean; Neely, David; Huggard, Peter; McKenna, Paul; Brenner, Ceri; Woolsey, Nigel; Wang, Wei-Min; Sheng, Zheng-Ming; Zhang, Jie
    This dataset includes experimental and numerical data from the manuscript 'Towards terawatt-scale spectrally-tunable terahertz pulses via relativistic laser-foil interactions'. The experimental data are obtained in the experiment titled “Intense terahertz radiation from picosecond laser-produced plasmas” (Application No.: 16110035, PI: David Neely), performed at Vulcan TAW. In this experiment, we demonstrate efficient production of terawatt (TW)-level THz pulses from high-intensity picosecond laser-foil interactions, and find the THz spectrum can be manipulated effectively by tuning the laser pulse duration or target size. A general analytical framework for THz generation is developed involving both the high-current electron emission and a time-varying electron sheath at the target rear, and the spectral tunability is found to stem from the change of the dominant THz generation mechanism. The THz radiation is applied to quantitatively diagnose the electron emission and the transient sheath, in good agreements with experimental measurements. Please see the file named “Data description” in the root directory of the attached zip file for a detailed description of the data contained therein. The data acquisition and analysis methods can also be found in the manuscript.
