Abstract
A laser beam irradiation apparatus includes a laser beam oscillation unit including a pulse laser beam oscillator for oscillating a pulse laser beam and a cycle frequency setting unit for setting the cycle frequency, an acousto-optic deflection unit for deflecting the optical axis of the pulse laser beam oscillated from the laser beam oscillation section, and a control unit for controlling the acousto-optic deflection unit. The control unit outputs a driving pulse signal having a predetermined time width including a pulse width of the pulse laser beam oscillated from the pulse laser beam oscillator to the acousto-optic deflection unit based on the cycle frequency setting signal from the cycle frequency setting section.
