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.

This repository entry is a central DOI for data related to the electromagnetic pulse (EMP) review paper titled: “Laser produced electromagnetic pulses: generation, detection and mitigation”. Data already in existing archives have the DOI provided. New data not in an archive is provided within this DOI. The review paper abstract is: “This paper provides an up to date review of the problems related to the generation, detection and mitigation of strong electromagnetic pulses created in the interaction of high power, high energy laser pulses with different types of solid targets. It includes new experimental data obtained independently at several international laboratories. The mechanisms of electromagnetic field generation are analyzed and considered as a function of the intensity and the spectral range of emissions they produce. The major emphasis is put towards the GHz frequency domain which is the most damaging for electronics and may have important applications. The physics of electromagnetic emissions in other spectral domains, in particular THz and MHz, is also discussed. The theoretical models and numerical simulations are compared with the results of experimental measurements, with special attention to the methodology of measurements and complementary diagnostics. Understanding the underlying physical processes is the basis for developing techniques to mitigate the electromagnetic threat and to harness electromagnetic emissions, which may have promising applications.” List of data: • Figure 5: Matlab code and input file used to generate figure provided in file “Figures-5-6_Poye-A.zip” • Figure 6: Matlab code and input file used to generate figure provided in file “Figures-5-6_Poye-A.zip” • Figure 18: experimental data used to generate figure is located at: http://dx.doi.org/10.5286/edata/1 • Figure 54: data used to generate figure is located at: https://doi.org/10.15124/a5d78c76-0546-412c-8b02-9edcb75efbb7 • Figure 55: data used to generate figure is located at: https://doi.org/10.15124/a5d78c76-0546-412c-8b02-9edcb75efbb7 • Figure 56: data used to generate figure is located at: https://doi.org/10.15124/a5d78c76-0546-412c-8b02-9edcb75efbb7 • Figure 57: data used in figure given in excel spreadsheet provided in file “Figures-57-58-59_Orion_Hillier-D” • Figure 58: data used in figure given in excel spreadsheet provided in file “Figures-57-58-59_Orion_Hillier-D” • Figure 59: data used in figure given in excel spreadsheet provided in file “Figures-57-58-59_Orion_Hillier-D”

Dataset summarising experimental results on the performance of a quartz polarisation rotator at low temperature
(2019) De Vido, Mariastefania
This dataset provides the experimental data on the performance of a 13.11 mm crystalline quartz rotator at low temperature. The rage of temperatures covered in this study is between 77 K and 325 K. We measured the temperature dependence of optical activity by propagating 1030 nm laser light collinearly with the optic axis. The effect on the polarisation state of the beam was assessed using an extinction method, where the beam propagates, in succession, through a polariser, the quartz sample and another polariser (analyser). The data is summarised in an Excel document. The first tab relates to data collected by keeping the transmission axes of the polariser and analyser parallel while the temperature of the quartz sample was varied. The other tabs contain the experimental data collected by varying the orientation of the transmission axis of the analyser while keeping the temperature of the quartz sample constant.

A modified uniformly redundant array (MURA) x-ray coded aperture imager and x-ray pinhole camera were used to image the soft x-ray emission from the rear surface of targets irradiated with the Vulcan Petawatt laser. The image data was captured on Fujifilm SR Imageplate scanned at 50 micron resolution. The coded aperture had a magnification of 10x with a working distance of 75 mm from the interaction. Filtering of 26 micron Aluminium was used as an optical light block as well as to attenuate the x-ray signal. The pinhole camera had a magnification of 20x with a 25 micron Tantalum pinhole with a 25 micron Beryllium filter and a working distance of 25 mm.
