In recent years, OPCPA and NOPCPA laser systems have shown the potential to supersede Ti: sapphire plus post-compression based laser systems to drive next generation attosecond light sources via direct amplification of few-cycle pulses to high pulse energies at high repetition rates. In this paper, we present a sub 3-cycle, 100 kHz, 24 W NOPA laser system and characterise its spatio-temporal properties using the SEA-F-SPIDER technique. Our results underline the importance of spatio-temporal diagnostics for these emerging laser systems.doi:10.1088/2040-8986/aaadc3 fatcat:pnaj5vn37faypnx5255pktpwwi
