A laser processing device ( 100 ) includes a laser oscillator ( 2 ), a laser machine ( 11 ) and a control means ( 1 ) for controlling the laser oscillator and the laser machine. The control means includes a storage means ( 50 ) for storing the processing program ( 60 ) for the work to be processed. The storage means has stored therein a required laser gas pressure value ( 72 ) for the laser oscillator in the laser processing operation, which value is determined in accordance with the processing specifics the work ( 20 ). The control means includes a laser gas pressure command transmission means ( 52 ) for transmitting a laser gas pressure command based on the required laser gas pressure value to the laser oscillator. This further improves the processing performance of the laser processing apparatus. Further, the control means may include a required laser gas pressure value adjusting means ( 55 ) for adjusting the required laser gas pressure value.
