The laser ablation system utilizes a variety of configurable laser beams to remove a substance from the surface of a substrate without damaging the underlying substrate. The present invention implements improvements to the laser ablation system to provide a gentle, yet thorough, ablating system through the use of a variety of rotating patterns. Furthermore, the system of the present invention is highly modifiable, such that a wide variety of parameters are adjustable to accommodate a wide variety of cleaning jobs.

A method of laser processing a component within an assembled apparatus using a boroscope, which includes a working head having first and second ends. A first optical fibre extends through the boroscope to a position between the first and second ends. A second optical fibre extends through the boroscope to the second end. A laser optical fibre extends through the boroscope. At least one lens is arranged between the first and second ends of the working head and a mirror is gimballed to the second end. The laser optical fibre directs laser light transmitted through the laser optical fibre onto the lens and then onto the mirror. A first LED is arranged at a position between the first and second ends of the working head and a second LED is arranged at the second end and an actuator device adjust the position of the mirror.

There is provided high power laser systems, high power laser tools, and methods of using these tools and systems for cutting, sectioning and removing structures objects, and materials, and in particular, for doing so in difficult to access locations and environments, such as offshore, underwater, or in hazardous environments, such as nuclear and chemical facilities. Thus, there is also provided high power laser systems, high power laser tools, and methods of using these systems and tools for removing structures, objects, and materials located offshore, under bodies of water and under the seafloor.

A hand-held therapeutic laser apparatus with a special opto-mechanical construction, which enables changeability of a front collimating lens to create different effective laser apertures. A smaller effective aperture has a comparatively higher radiant flux density for treatment of a small area that requires a higher energy dose, while a larger effective aperture facilitates treatment of a large area at a relatively reduced radiant intensity.

A boroscope has a first end and a second end and the first end of the boroscope has an optical fiber, a light source, a lens, a beam expander and a transmissive diffractive optical element. The optical fiber extends from the first end of the boroscope to the second end of the boroscope. A laser optical fiber extends from the lens at the first end of the boroscope to the second end of the boroscope and a laser source is arranged to direct a laser beam into the laser optical fiber. The beam expander is provided between the laser optical fiber and the lens and the lens is provided between the beam expander and the transmissive diffractive optical element. The transmissive diffractive optical element is arranged to produce a laser beam with a predetermined shape and a focal length probe extends from the first end of the boroscope.

A method of forming an internally-arranged laser-beam weld from within a composite structure. The method includes arranging a welding apparatus within an internal passage of the composite structure, and emitting a laser beam from the welding apparatus to form the internally-arranged laser-beam weld between layers of the composite structure.

A laser marking system for marking a product includes a marking head having an electromagnetic radiation steering mechanism configured to steer electromagnetic radiation to address a specific location within a two-dimensional field of view. The electromagnetic radiation steering mechanism comprises a first optical element having an associated first actuator configured to rotate the first optical element about a first rotational axis to change a first coordinate of a first steering axis in the two-dimensional field of view and a second optical element having an associated second actuator configured to rotate the second optical element about a second rotational axis to change a second coordinate of a second steering axis in the two-dimensional field of view. The electromagnetic radiation steering mechanism comprises an electromagnetic radiation manipulator configured to introduce a difference between a first angle and a second angle (defined between the first and second rotational and steering (respectively) axes).

On-demand laser marking device manufacturing method and laser marking device obtained by said method

Method of producing equipment for marking products by laser, comprising the steps of: having at least one base plate; having various types of modules in which equipment components are grouped; having casings, rear covers and front covers that can be attached to said base plate; selecting modules from each of the different module types; removably attaching the selected modules to the base plate; attaching the casing, rear cover and front cover to the base plate.

A system for performing a laser peening application on a workpiece. A purge system is included with the system to provide a compartment housing combustion sources with compressed air so that the compartment has an increased air pressure. Also, a method of operating the system in which power is provided to the system, but only the purge system operates initially. Only after the purge system has bene operating, are the other subsystems and components of the systems, like the laser, provided with operational power.
