Laser beam machine

Abstract

Abstract PURPOSE:To obtain a titled machine for reducing an output loss of a laser, perform plural laser machining and improve the productivity by providing a rotary chopping reflecting mirror for making a part of a laser beam transmit and a total reflecting mirror of a transmitting beam on a laser beam path, and converting it to a pulse laser beam. CONSTITUTION:A continuous laser beam 8 of a laser beam path is reflected and divided into pulse laser beams 8A, 8B by a rotary 3 chopping mirror 4 for making a part of said beam transmit 4a and reflecting totally a part of same, and a total reflecting mirror 5, and plural objects 7 to be worked are brought to pulse laser machining, respectively. A laser oscillator can execute a continuous oscillation, reduces an output loss of a laser, can perform plural laser beam machining, and improves the productivity. In this regard, it is also possible to change a shape of a transmitting beam hole of the chopping mirror and to increase its number to three pieces or more.
