Characterization of the fluence distribution in the focus of ultra-high intensity laser beam is important for investigating laser-matter interactions. We studied the fluence distribution in the laser beam focus utilizing the direct method of ablative imprints.
The method is based on creating cross-sections at varied levels of the fluence distribution. We present experimental results obtained at two distinct ultra-high intensity laser facilities, namely, Prague Asterix Laser System (NIR and VIS spectrum) and European XFEL (X-ray spectrum).
In NIR and VIS spectrum this is a proof of concept measurement. We discuss the use of ablative imprints method.
