Extreme Light Infrastructure – Nuclear Physics (ELI-NP), the new Research Center under construction in Bucharest-Magurele, will use extreme electromagnetic fields, produced by a high power laser system (2x10PW) and by a very brilliant gamma beam (up to 20 MeV), for nuclear physics research. The status of the Project implementation, which started in 2013, will be presented. The new Center,...
As the three ELI pillars in Romania, Czech Republic and Hungary and other large scale facilities like the Apollon system are becoming a reality, unfathomable possibilities not envisaged in the original proposal are coming up. They stem from the combination of peak power, flattop and low beam divergence. The most intriguing one is the capacity to compress petawatt pulses to the single cycle...
A possibility of implementation nonlinear optical effects to pulse shortening and temporal intensity contrast ratio enhancement of high energy (~kJ) femtosecond laser pulses will be discussed. Experimental results on temporal recompression from 57fs to 22 fs in a part of a petawatt level laser beam at laser system PEARL will be presented. Theoretical analyze of an influence of a residual...
ELI-Beamlines will be the high-energy, repetition-rate laser pillar of the ELI (Extreme Light Infrastructure) project. It will be an international facility for both academic and applied research, slated to provide first user capability since the beginning of 2018. The main objective of the ELI-Beamlines Project is delivery of ultra-short high-energy pulses for the generation and applications...
At the newly formed Laser Plasma Interactions group at UCI, a wide variety of unique laser capabilities is becoming available for use. The 3000 square foot lab is equipped with HEPA filtering and temperature/humidity stability to ensure robust laser operation. A 30 fs Ti:Sapphire regenerative amplifier is at the heart of the laser facility, operating at high repetition rates of 1 kHz and peak...
Extreme light at Center for Relativistic Laser Science (CoReLS) in Korea has been developed and currently its’ output power reaches 4 PW. The output energy and the pulse duration are 83 J and 19.6 fs, respectively after the pulse compression. In addition, we have carried out the pulse compression experiment with thin fused silica plates using a 30 fs, 100 TW laser pulse. After compensating the...
An experimental platform is presented, aimed at studying the impact of laser-driven high-energy protons on biological objects. The platform has been developed using the PW-class PEARL laser facility (IAP RAS Nizhny Novgorod, Russia). Pilot experiments were performed using laser-accelerated protons having up to 25 MeV energy, and we demonstrated the possibility of transferring doses up to 10 Gy...
Proton radiation therapy for patients started in 1954. Until today more than 150000 patients have been treated. First decades of proton therapy were focused on treatments of skull base and (para)spinal tumors, e.g. chordomas, chondrosarcomas and sarcomas. Choroidal melanomas and prostate cancer built the largest groups of entities during the past 20 years.
Nowadays proton radiation therapy is...
Abstract
The idea we propose is based on avoiding the direct interaction between the laser and the atomic/molecular components of the thin film which the laser interacts with, in the purpose of saving the energy of the emergent laser. For this purpose the emergent laser interacts with free electrons generated by an electron source, then the laser accelerated electrons by the laser attract...
The efficient, post-compression of high-energy Petawatt (PW) scale laser pulses toward the fundamental limit of a single-cycle pulse duration offers a path to extreme peak intensities without the need for adding additional costly energy amplification. Instead the existing pulse energy is redistributed in the generation of additional spectral bandwidth and further compressed through subsequent...
Radioisotopes applications in nuclear medicine are in the field of both diagnosis (oncology, cardiology and neurology) and therapy (oncology). Molecular imaging probes, a special class of radiopharmaceuticals, targets specific biochemical signatures associated with disease and allow for non-invasive imaging on the molecular level. Because changes in biochemistry occur before diseases reach the...
Introduction: ELI-ALPS will provide laser accelerated electron and ion beams with unique, ultra-short pulses and ultra high dose rate parameters to examine the effects of different ionizing radiations on cells, zebrafish and rodent models.
Aims: Our aims are to develop the appropriate dosimetry system and to validate preclinical models for Relative Biological Effectivity (RBE)...
The field of high peak power lasers have seen considerable developments over the past years. Several lasers delivering more than 1 PetaWatt peak power at significant pulse rates have become available and there are several 10 PW lasers in construction worldwide.
In addition to the improvement of performance (higher peak power, shorter pulse duration, higher repetition rate), there are also...
The aim of the presentation is to describe actual lasers applications in ophtalmology, for therapy and diagnostic. Different eye diseases are explained physipatologically and therefore the use of lasers based on their specific laser-tissue interaction. The goal is for the audience to have an idea about the importance of lasers for our vision.
