Abstract
A machining device comprises laser beam machining means for shining a laser beam to a workpiece. The laser beam machining means includes laser beam oscillation means, laser beam modulation means, and laser beam shining means. The laser beam modulation means includes laser beam pulse width setting means for converting the laser beam oscillated by the laser beam oscillation means into a pulse laser having a pulse width of 1,000 ps or less.
