To quantify an increase in the spectral intensity in a narrowing bandwidth the so called Spectral brightness is calculated: To quantify an increase in the spectral intensity in a narrowing bandwidth, the so called Spectral brightness is calculated:
$`\text{Spectral brightness} = \frac{\text{Single shot intensity [uJ]}}{\text{Single shot spectral FWHM [eV]}}`$ $`\text{Spectral brightness} = \frac{\text{Single shot intensity [uJ]}}{\text{Single shot spectral FWHM [eV]}}`$
At Aramis the current channel used for the single shot pulse intensity is: At Aramis, the current channel used for the single shot pulse intensity is:
`SARFE10-PBPG050:FAST-PULSE-ENERGY` `SARFE10-PBPG050:FAST-PULSE-ENERGY`
and the spectral FWHM uses the single shot spectral width. The result channel name is: and the spectral FWHM uses the single-shot spectral width. The result channel name is:
`<SPECTROMETER:DEVICE>:FIT-BRT` `<device name>:FIT-BRT`
indicating the data uses a Gaussian fit. Beware this data is only meaningful if the spectral intensity distribution is near Gaussian. indicating the data uses a Gaussian fit. Be aware that this data is only meaningful if the spectral intensity distribution is near Gaussian.
