Description
Key words: High Average Power, High Peak Power, High Energy, Ultrashort Pulse, OPA/OPCPA, Ti:Sapphire, Ytterbium
Amplitude provides the broadest portfolio of ultrafast lasers based on diverse existing technologies: Ytterbium, Ti:Sapphire, Neodymium, OPCPA based systems... We report here the latest achievements in the development of high energy ultrafast femtosecond lasers along with our roadmap aimed at ramping up the repetition rate, to address in particular the need for compact, lab-based secondary sources.
We will first report our recent achievements in high energy, high peak power Ti:Sapphire laser systems together with our roadmap towards 100Hz operation rate at hundreds of TW level. This evolution is enabled by the development of our last-generation diode-pumped high energy nanosecond Nd:YAG pump lasers at 100Hz.
For lower peak power applications, high repetition rate and high average power are currently better addressed by Ytterbium technology. After a brief introduction of Yb-based lasers available at Amplitude, we will show how applications like secondary sources and related facilities can benefit from this mature technology, including the flexibility added by technologies such as post compression to reach even higher peak powers, or Optical Parametric Amplification (OPA) for wavelength tunability.
We will finally conclude by presenting one recent achievement at the LRCS in Amiens (France) consisting in a compact kHz laser-plasma X-ray source1 at 17.4 keV integrated in an all-laser-driven pump-probe architecture for the time-resolved study of perovskites degradation, based on the above-mentioned technologies available at Amplitude.
