Abstract
A laser beam irradiating apparatus includes a laser oscillator configured to emit a laser beam, a first polarization beam splitter configured to separate the laser beam into a first laser beam of s-polarized light and a second laser beam of p-polarized light, a first spatial light modulator configured to modulate the first laser beam according to a phase pattern, and emit the resulting first laser beam, a second spatial light modulator configured to modulate the second laser beam according to a phase pattern, and emit the resulting second laser beam; a second polarization beam splitter configured to synthesize the first laser beam emitted from the first spatial light modulator and the second laser beam emitted from the second spatial light modulator, and an imaging unit configured to image the synthesized laser beam, and irradiate a target object with the resulting laser beam.
