The title of presentation:
The Tewati laser system and its applications:
laser-generated neutrons, laser cutting, and x-ray computer tomography

Short abstract of the presentation:
In this talk, I will present the third-generation of the laser  
systems, operating now at 100Hz repetition rate, ever built at Tewati  
Lab.
In the so-called short-pulse branch, pulses with a duration of 9 fs  
and an energy of 0.2 mJ are generated. In the high-intensity branch,  
after the installation of the compressor chamber, pulses with an  
intensity of one and a half TW at a central wavelength of 800 nm are  
to be achieved. The laser system has already been successfully used to  
develop an ultra-thin, several hundred nm thick liquid jet target  
system, which is a key component of the laser neutron source designed  
and built by the National Laser Transmutation Laboratory. Femtosecond  
precision cutting was also developed to manufacture another key  
component, the neutron converter.
In the frame of the Cooperative Technologies National Laboratory,  
high-intensity laser pulses from the Tewati laser were directed onto a  
tape target system to produce X-rays. We will be using the  
laser-generated X-rays to take computed tomography (CT) images of  
drone components.
There will be an opportunity for a visit to the laboratory at the end  
of the seminar.

Everyone is welcome to attend.

Dr. Mária Csete
