【Abstract】 A novel experiment has been carried out for studying the interaction between ultra short intense laser pulses and glass micro capillary. The X ray emissions from variety capillary lengths and in different laser energy have been measured and analyzed. Experimental results show that owing to the light guide of capillary, the intensity of X xay emission is increased intensively when the capillary length is longered. The plasma temperature is estimated by the recombination edge method and found that the temperature is increased with the increasing of the laser pulse energy.更多还原
