1. A pulse oscillating type solid laser unit that has a laser unit body whose exciting source is a laser diode that emits light in a principal energy absorbing spectrum of a solid laser activated media, and characterized by that prior to radiating laser light outside the laser unit body as a calibrating operation of a pulse laser output value, specified several varieties of rectangle pulse current values are conducted to a laser diode inside the pulse oscillating type solid laser unit so as to pulse-oscillate the laser unit body, a mean laser output value in each rectangle pulse current value is measured by the use of a laser output measuring instrument arranged inside the laser unit body so as to obtain a mean laser output value data, and in case that the laser output light is radiated outside the laser unit body, a pulse current value linear-predicted based on an obtained mean output value data is conducted to the laser diode so as to obtain a desired pulse laser output value.

The invention provides a laser beam machine having a light path duct with improved dust proof property. A light path system 1 of a laser beam machine comprises a light path duct 10 having a U-shaped cross-section with the upper end opened, wherein the opening portion is covered by a steel belt 30. The laser beam extraction unit 50 traveling on the light path duct 10 in the direction of arrow A elevates the steel belt 30 and extracts the laser beam from the light path duct 10. The steel belt 30 has a guiding projection 32 disposed at the center thereof. The laser beam extraction unit 50 has a guide roller 64 disposed below the steel belt 30 and a guide roller 62 having a V-shaped groove 62a for engaging the projection on the steel belt 30, thereby preventing displacement of the steel belt.

An energy collector is used to assist a laser coupling process by reducing the amount of output power of a laser that is used to modify a device attaching element. The energy collector includes an energy collector tip configured to be placed proximate to a device attaching element during the laser coupling process. The energy collector tip is configured to receive laser energy reflected from the device attaching element during the laser coupling process and is formed from a material that converts this reflected energy to heat. Sufficient thermal coupling is created between the energy collector and a surface to provide a conductive pathway for the energy, which has been converted to heat, between the energy collector and the device attaching element.

摘要:
A thermal cutting machine and a cutting method using the same are described, which employ a simple, long-life torch hood for effectively shutting off spatter, the torch hood enabling easy supervision of the cut condition of a workpiece and easy replacement of the consumable parts of the torch. In the thermal cutting machine for cutting a metal by a plasma arc or laser beam generated from the torch, a hood liftable by an actuator is disposed so as to surround the torch and a control unit is provided for giving an instruction to the actuator to lower the hood to a torch-shielding position.

A laser welding device includes a laser that generates a laser beam, an optics, and a limiting apparatus. The optics has a focal length of at least 200 nm and being configured to focus the laser beam onto a processing zone of a workpiece. The limiting apparatus limits a mixture of welding gases and heated ambient air, produced during laser welding, within the laser beam to a region that is less than the focal length from a surface of the workpiece.
摘要:
A system and method for manufacturing welded structures comprises components to be welded, a welding additive material which, before the welding, has a shaped profile and the shaped profile is disposed between components to be welded and conforms with at least one of the components to be welded. At least one heat source is used in the method to weld the components, producing a weld seam on at least one side of one of the components.
