Abstract
A laser irradiation apparatus includes a controller configured to calculate a predicted movement position into which a target is predicted to move at a future specific time, a transmission laser source configured to generate a transmission laser, irradiation optics configured to emit the transmission laser to the target and emit a search laser to the predicted movement position and wavefront correction optics. The wavefront correction optics are configured to correct a wavefront of the transmission laser at the future specific time based on observation light that returns when the search laser is emitted to the predicted movement position.
