Techniques for generating high energy bright short-pulse Ka X-rays have been rapidly developed in recent progress made in utilizing intense ultrashort laser pulses. The soft X-ray laser (XRL) is also generated from the Laser-Produced Plasma (LPP). A highly spatial coherent XRL is generated by the oscillator-amplifier configuration with two targets. Use of X-ray focusing optics has resulted in focused X-ray beams of submicron spot size being achieved in soft and hard X-ray regions. The short duration of laser produced plasma source could be used as a new source in contrast to conventional X-ray sources in investigating the mechanism of the affect of radiation on biological cells.
