Chirped pulse amplification (CPA) technique was realized in Nd:YVO4 and Nd:YAG amplifiers. The front-end of the system consists of an Yb-doped fiber-optic master oscillator and a chirped fiber Bragg grating stretcher with a chain of Nd-based solid-state amplifiers followed by a grating compressor with custom high-dispersion multilayer dielectric gratings. This allowed us to implement a relatively compact and moderately complex master oscillator power amplifier (MOPA) layout. 85 mJ of sub-20 ps pulses at 1 kHz repetition rate was obtained at the output. The amplifier features favourable parameters for OPCPA pumping.

AbstractThe origin and characteristics of near-microcoulomb multi-MeV electrons accelerated by short pulse lasers interacting with near-critical density plasma in self-formed channels are studied using three-dimensional particle-in-cell simulations. According to the analysis on interaction phenomena and electron dynamics, the dominant mechanism turns out to be direct laser acceleration, which ensures the outstanding energy coupling. Additionally, self-channeling is found to be a decisive factor for the acceleration performance, as electrons obtain ultra-high energy through betatron resonance inside the channels. In our findings, by using a relativistic short laser pulse and near-critical plasma, a large amount of energetic electrons can be generated, presenting a promising and accessible route to ultraintense, high-spatial-resolution radiation pulses.
