Thales is delighted to attend SPIE Photonics West. This 2021 edition is held online only.
At SPIE Photonics West online exhibition, Thales will present its solutions and products. Visit our virtual booth and discover there our latest products RHEA and THEIA which provide breakthrough in performance and reliability for industrial and scientific applications. To know more about these lasers please get in touch with our team for a live chat after registration at https://spie.org/PW21/registration/attendeeinformation.
From March 6 to 11 in the SPIE Photonics West Digital Forum, you are also invited to watch Thales on-demand video technical presentations presented by some of Thales' laser experts and partnering scientists.
Presentation 1 – Paper 11664-24
"30 TW and 33 fs pulses delivered by a Ti:Sa amplifier system seeded with a frequency doubled fiber laser "
These results have been obtained in partnership with Alphanov (FR)
Presented by Sébastien Laux - Senior Bid Manager
Abstract
We report a full experimental comparison study on the injection of a Ti:Sa multi-TW amplifier chain with a standard 15 fs Ti:Sa oscillator and a 35 fs frequency doubled fiber oscillator. The study highlights that the Ti:Sa oscillator with high performances in term of pulse duration and spectral width can be replaced by the frequency doubled fiber oscillator to seed Ti:Sa amplifier chains without almost any compromise on the output pulse duration and the picosecond contrast. Finally, we demonstrate for the first time of our knowledge a 30 TW and 33 fs Ti:Sa amplifier injected by a fiber oscillator.

Presentation 2 –Paper 11666-3
"10 petawatts laser operation within beam transport section at ELI-NP"
Presented by François Lureau - Programme Manager
Abstract
As major milestone of commissioning phase of beam transport section for the 10 petawatts beamlines of Extreme Light Infrastructure Nuclear Physics (ELI-NP) located in Magurele (Romania), we have propagated the beam throughout the beam transport section and measured its energy as well as its pulse duration after compression at full energy and full aperture. 10 consecutive laser pulses have been shot at a repetition rate of 1 shot per minute with compressed pulse energy ranging between 241 and 246 Joules while pulse duration has been measured at 23 fs leading to the first ever operation above 10 petawatts peak power

Presentation 3 – Paper 11664-20
"Thick-disk TiSa gain module for high average power amplifier "
Presented by Sandrine Ricaud - Engineering Laser Manager
Abstract
We present a new concept of thick-disk TiSa amplifier developed for increasing repetition rate of multi-TW laser at 100Hz repetition rate. Thanks to the management of thermal lens and transverse lasing effect, the design of 300mJ amplifier at 100Hz repetition rate is presented. The full characterization of the gain module is done, and the upgrade for J class amplifier is presented. Those amplifiers are pumped by new laser developed by Thales, THEIA family, emitting more than 700mJ at 532nm for 100 and 200Hz repetition rate.
