The delay circuit unit may receive a trigger signal, output a first delay signal obtained by delaying the trigger signal by a first delay time, and output a second delay signal obtained by delaying the trigger signal by a second delay time. The first trigger-correction unit may receive the first delay signal and output a first switch signal obtained by delaying the first delay signal by a first correction time. The second trigger-correction unit may receive the second delay signal and output a second switch signal obtained by delaying the second delay signal by a second correction time. The clock generator may generate a clock signal that is common to the delay circuit unit and the first and second trigger-correction units.

The timing detector may be configured to detect a first passage timing at which the first pulse laser beam passes a first position and a second passage timing at which the second pulse laser beam passes a second position. The controller may be configured to control a first trigger timing for the first laser apparatus to emit the first pulse laser beam and a second trigger timing for the second laser apparatus to emit the second pulse laser beam based on the first passage timing and the second passage timing.
