An improvement of laser-focused peak intensity has been achieved in a JAERI 100 TW Ti:sapphire chirped-pulse amplifier chain with a feedback controlled adaptive optics system at a 10 Hz repetition rate. Independent measurements of optical parameters of the laser pulse and an experimental tunneling ionization ratio of He atom with laser energy scaling have practically confirmed an ultrarelativistic intensity of over 1020 W • cm-2. © 2007 Springer-Verlag New York.
