Abstract:
1. An ultra-short ultra high-intensity pulse laser generating apparatus comprising: a pulse laser providing unit generating ultra-short ultra high-intensity pulse lasers, stretching a pulse width of each of the pulse lasers, and selectively providing a laser pulse having a pre-set polarization angle; a polarization characteristics controlling unit splitting the laser pulse provided from the pulse laser providing unit into S polarized component light and P polarized component light, varying a phase difference and an amplitude difference between the S polarized component light and the P polarized component light, and optically coupling the S polarized component light and the P polarized component light to generate a laser pulse having varied polarization characteristics; and a pulse compressing unit compressing a pulse width of the laser pulse having the polarization characteristics varied by the polarization characteristics controlling unit and outputting the laser pulse.
