Claims

[Scope of utility model registration request]

The above-mentioned opening of the pressurizing chamber is formed at the tip of the processing head main body in the direction of the laser beam axis, parallel to the laser beam axis, opens toward the tip, and is filled with a pressurized fluid that is always kept at a constant pressure. A laser processing device characterized in that the nozzle is configured such that the base end side thereof is fitted and slidable liquid-tightly in the laser optical axis direction.
