Data associated with the manuscript 'Efficient and stable second harmonic conversion, at the 0.5 kW-level, of a diode-pumped Yb:YAG laser'
No full textThis 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.European Union’s Horizon 2020 (739573).

Demonstrations of fast approximate variable-width broadening
No full textWe have developed a fast approximate method of applying variable-width broadening to spectral data.
This dataset contains demonstration scripts which generate the plots for a related academic manuscript. They also reproduce the parametrisation of polynomial fits to the relationship between the approximation error and the scale factor between broadening kernels used in the method.
Some of the scripts use the implementation in the Euphonic library:
to reproduce published results use Euphonic v1.3.0
- https://pace-neutrons.github.io/Euphonic/versions/v1.3.0.html
- https://github.com/pace-neutrons/Euphonic/releases/tag/v1.3.0
Most of the scripts are written in Python. One Bash shell script is also included which needs to call the euphonic-powder-map program included in the Euphonic package. A Makefile is provided so that all plots can be generated with "make plots" using GNU Make.
.yaml datafiles were derived from data in the Kyoto phonon database
("phonondb") under a CC-by license: the Phonopy calculation
directories were downloaded and Phonopy was run with =--include-all=
and =--nac= options to create .yaml files containing all the
information needed by Euphonic

Molecular simulation trajectories and atomic interaction descriptions of 1,1,1,2-tetrefluoroethane liquids.
No full textData on raw atomic trajectories (5 ns) produced by DL_POLY molecular dynamics simulation package. The system model is described in the DL_F Notation, which contained chemical information of the atoms. The DL_ANALYSER Notation for Atomic Interaction (DANAI) is used to annotate the atomic interaction networks in the system, to provide an overall view of the molecular interaction behaviour.
The dataset contains five different sets of simulation data, over a range of temperatures: 203K, 233K. 263K. 293K and 323K.EP/L015285/1
