METHOD AND APPARATUS FOR CONTROLLING LASER PULSE AND METHOD AND APPARATUS FOR GENERATING X-RAY

Japanese Patent JP3698677

B2

PROBLEM TO BE SOLVED: To provide an X-ray generator having a mechanism of regulating pulse lasers so as to selectively control the intensity of X-rays, more particularly the intensity of the X-rays of a required specific wavelength with an apparatus for generating the X-rays by irradiating a target with the ultra-short light pulse lasers, etc.
SOLUTION: The generation of the X-rays of the specific wavelength is controlled by measuring the intensity characteristics of the X-rays generated by an X-ray spectroscope 10, feeding the result of the measurement back to a wave front phase regulating mechanism 3, regulating the wave front state of the laser beam and generating the space intensity distribution patterns of the laser beam in the position where the laser beam is condensed to the target 7 and control parameters are adjusted in such a manner that the intensity of the X-rays is optimized in accordance with the measurement result of the X-ray intensity characteristics.
