Abstract
A laser processing machine includes: a variable focal length optical system in which a focus position is periodically changed in response to a drive signal to be inputted; a position-detection light source configured to emit a detection light onto a workpiece through the variable focal length optical system; a light detector configured to receive the detection light reflected on the workpiece and output a light detection signal; a signal processor configured to output a synchronization pulse signal in synchronization with the focus timing when the detection light is focused on the surface of the workpiece in accordance with the inputted light detection signal; and a laser oscillator configured to oscillate a pulse laser beam in accordance with the inputted synchronization pulse signal to radiate the pulse laser beam on the workpiece through the variable focal length optical system.
