Abstract

To widen the field of application of the x-ray laser, higher repetition rate of the x-ray laser is needed. Moreover, the study on effective generation of x-ray laser by optimizing pumping conditions is very important in order to achieve the high repetition rate. At Japan Atomic Energy Agency (JAEA), we have been developing a new type of high repetition rate x-ray laser driver using zigzag slab amplifier for high repetitive x-ray lasing and an OPCPA (Optical Parametric Chirped Pulse Amplification) preamplifier for optimizing x-ray lasing conditions instead of a regenerative amplifier. We are now studying the optimization of pumping conditions for efficient x-ray lasing by the use of pump laser with very high pulse contrast from the OPCPA preamplifier. And we are planning to perform applications using the high repetition rate x-ray laser such as x-ray holography.
