Abstract :
Three key techniques have been demonstrated in small scale. Cryogenic Yb:YAG-ceramic DPSSL operated in high energy fluence at high optical efficiency for a repeatable high-pulse-energy pump source. Optical parametric chirped-pulse amplification (OPCPA) with a spatially random-phased pump beam was demonstrated assuming multi-beam pump in kilo-joule-class. Partially deuterated KDP crystals showed broad spectral gain bandwidth for few cycle pulses in non-collinear OPCPA and were successfully grown.
