Schustr, P. ; Fibrich, Martin ; Polan, Jiří ; Rus, Bedřich ; Dostálová, M. ; Valdislav, P. ; Simek, J.
We present design and operational prototype of cryogenic cooling system based on Bryton's cycle for 10J/10Hz Yb:YAG multi-slab laser system at ELI-Beamlines project.
Safety aspects of usage of flammable and toxic gases in high power laser accelerator experiments
Procházka, Petr ; Prokůpek, J. ; Perales, B.
High power laser accelerators are promising technologies that can effectively decrease the space and potentially cost of the particle acceleration experiments. For many of them there is a technical demand to use flammable and toxic gases as targets for lasers or for accelerated particles. Their usage, however, brings many challenges for design of the technology and safety management system of the facility.
High hazards in laser experimental work: challenges for safety management of laser research facilities
Procházka, Petr ; Olšovcová, Veronika ; Margarone, Daniele ; Přeček, Martin ; Korn, Georg
Research developing and exploiting a technology of high power laser systems belongs among the most progressive parts of modern physics. Usage of the laser technology is associated with many kinds of hazards that pose significant risks to both scientific and technical professionals. Therefore, to ensure the personnel safety, the hazards needs to be addressed and thoroughly evaluated to allow not only rigorous design and construction of building and technology but also effective implementation of operational and work procedures. This paper describes the most significant hazards present within the experimental laser facilities.
Hollow-duct radiation delivery system investigation
Fibrich, Martin ; Rus, Bedřich ; Kramer, Daniel
Investigation of hollow-duct structure for high-power laser-diode-array-radiation delivery into the end-pumped large-aperture gain media is reported.
Design of hybrid compressor for a 10PW laser
Kramer, Daniel ; Novák, Jakub ; Rus, Bedřich
The ELI beamlines facility wiil house a 10PW laser with ultrashort pulse duration. The laser damage threshold of the coating limits the minimum size of the last compression grating. Due to production restriction the last grating has to be tiled. The design was produced in order to minimize the total number of gratings in the compressor together with the spatial requirements.
