Abstract

PURPOSE:To shape an optical pulse waveform of a desired intensity distribution by providing a beam splitter for allowing the optical pulse waveform to branch, and plural reflecting mirrors for giving a phase difference to one branched optical pulse waveform and synthesizing said optical pulse waveform with the other branched optical pulse waveform by the beam splitter. CONSTITUTION:An optical pulse waveform L is allowed to branch to two optical pulse waveforms L11, L12 by a beam splitter 11, and the optical pulse waveform L11 reflected by the beam splitter 11 is given a suitable phase difference by reflecting mirrors 12-15, and thereafter, synthesized with the optical pulse waveform L12 by the beam splitter 11, and becomes an optical pulse waveform L13. As for the phase difference in the case, by controlling an interval of the beam splitter 11 and the reflecting mirrors 12, 15, a mutual interval of the reflecting mirrors 12-15, and the number of reflecting mirrors, and varying the optical path length, a prescribed value can be obtained. In such a way, the optical pulse waveform of a desired intensity distribution is obtained.
