INFLPR is involved in two Joint Research Activities (JRAs):
●  Innovative Laser Technologies – ILAT, and
●  Laser-driven High Energy Photon and Particle Sources towards Industrial and Societal Application - LEEP.

●  ILAT undertakes three main objectives:
(i) Solve crucial laser physics bottlenecks in order to make available to LASERLAB  -EUROPE’s future users a new generation of laser sources with improved performances;
(ii) Involve industrial partners;
(iii) Provide sizeable synergies with European Strategy Forum on Research Infrastructures (ESFRI) in terms of both strategic laser technology development and training of a new generation of laser physics experts.

By improvements of high peak power laser driver performances in terms of increasing stability, efficiency, energy, repetition rate, power and reliability, a next generation of radiation sources in the THz-Mid-IR and XUV-X rays will be made available for an increasingly number of complex and sophisticated applications.

In the framework of ILAT there are five objectives for the development of future advanced radiation sources:
1. High Average and Peak Power Laser Technology Development;
2. Overcoming the bottlenecks of few-cycle and high peak power lasers;
3. Advanced coherent XUV and X-Ray sources;
4. Next generation high power and high rep-rate Mid-IR sources;
5. Next generation high power THz sources.

INFLPR will contribute to achievement of the fifth objective regarding a more effective design of high power THz sources by appropriately tailoring the driving laser wave packet in order to obtain extended uniform high electron density plasma strings and by understanding of the nonlinear propagation and THz generation mechanisms inside the laser-plasma strings using numerical codes.

●  The objectives of the LEEP JRA are:
(i) To optimize secondary high energy sources for specific and well identified applications of high industrial and societal relevance;
(ii) To contribute to the implementation of proof of principle experiments/set-ups in EU facilities to test some of the most promising concepts/applications;

(iii) To leverage on national activities to shape and to focus the European landscape on applications of laser driven high energy photons and particle sources.

In the framework of LEEP there are four tasks:

1. Radiotherapy and radiobiology applications of laser based electron accelerators;

2. Development and applications of compact light sources for imaging;

3. Radiotherapy and radiobiology applications of laser based proton beams;

4. Advanced instrumentation and targets for applications of laser driven high energy photon and particle sources.

INFLPR will contribute to achievement of the fourth task through characterization and control of the spatial and temporal properties of high-energy radiation and particle laser-driven sources.
