Resumo
IPEN's Center for Lasers and Applications utilized laser pulses produced by a hybrid
Ti:Sapphire/Cr:LiSAF CPA system. The CPA frontend is a Quantronix Odin laser that generates
50 fs, 1 mJ pulses at 1 kHz. The system has been modified to allow the extraction of the amplified,
uncompressed pulses, which are then sent to an in-house, custom-designed Cr:LiSAF multipass
amplifier [1,2] and compressor, generating up to 0.5 TW pulses at 5 Hz. This system is shown in
Fig. 1, and is being upgraded replacing the Cr:LiSAF by a multipass Ti:sapphire amplifier, aiming
to obtain near-TW pulses at 10 Hz. As a first target, the upgraded system will aim to investigate the production of medical
radioisotopes by photonuclear reactions triggered by Bremsstrahlung gamma photons from
electrons; IPEN is developing a laser wakefield accelerator (LWFA) – potentially the first one in
Brazil –, to initially operate in the self-modulated regime (SM-LWFA). With this goal, multiple
subjects related to the SM-LWFA are being addressed ranging from theoretical works and PIC
simulations [3] to the in-house development of de Laval nozzles [4], and plasma diagnostics [5].
Currently, IPEN intends to establish a high-intensity, multi-user laser facility that will be equipped
with a 15 TW, 35 fs pulse laser system at 10 Hz. The system will be modular, featuring a main
oscillator, a temporal stretcher, a regenerative and 2 multipass amplification stages, and a pulse
compressor, capable of being upgraded to 30 TW. The system, the experimental setup and the
diagnostics are designed to be versatile, prepared for supporting particle accelerations processes
and even extreme conditions, a platform for multi-users experiments.
