Abstract

X-ray emissions form Xe cryogenic target, Kr cryogenic target and Xe gas target were studied and compared. A high average high peak brightness pulsed Nd:YAG laser was successfully developed as a driver for high average power laser plasmas x-ray sources. A target system that can supply cryogenic targets without interrupting the operation was also developed. Any discrete images of fast debris of several 10 micrometers or more in diameter were not observed in backlighting experiments. A new approach to extinguish the fast debris from the cryogenic target by using 'laser shower' was proposed and proved to be practical.
