|System and high-power, pulsed ring fiber oscillator|
A ring laser includes a large-core rare-earth-doped fiber ring-connected with a free-space path having an electro-optic switch, output coupler, and intracavity band-pass filter to enforce lasing operation in narrow wavelength range. In some cavity-dumped modes, the laser is configured in a similar manner, except that an output coupler is omitted since the optical power is extracted from the laser cavity by the electro-optic switch itself.

|Multi-chip vecsel-based laser tunable independently at multiple wavelengths|
A laser device capable to simultaneously generate light at multiple wavelengths that are independently (and, optionally, simultaneously) tunable without a limit of how small a spectral separation between such wavelengths can be made is enabled with the use of a laser-cavity network that (i) contains multiple spatially-distinct laser cavity portions all of which have at least one spatial region of the cavity network in common and (ii) is defined by such optical elements that prevent the intracavity amplification of light at first and second of multiple wavelengths at the expense of the same laser gain medium. Each of the distinct cavity portions contains a dedicated laser chip supporting the generation of light at a corresponding wavelength.
|Advanced excimer laser annealing for thin films|
The present disclosure relates to a new generation of laser-crystallization approaches that can crystallize si films for large displays at drastically increased effective crystallization rates. The particular scheme presented in this aspect of the disclosure is referred to as the advanced excimer-laser annealing (aela) method, and it can be readily configured for manufacturing large oled tvs using various available and proven technical components.

|Localized atmospheric laser chemical vapor deposition|
An atmospheric, laser-based chemical vapor deposition (lcvd) technique provides highly localized deposition of material to mitigate damage sites on an optical component. The same laser beam can be used to deposit material as well as for in-situ annealing of the deposited material.

|System and methods for depth detection in laser-assisted ophthalmic procedures|
Embodiments of this invention relate to systems and methods for automatic depth (or z) detection before, during, or after laser-assisted ophthalmic surgery. When performing ophthalmic laser surgery, the operator (or surgeon) needs to make accurate and precise incisions using the laser beam.
|Spark plug and manufacturing the same|
A method of manufacturing a spark plug that includes a metallic shell, an insulator, a center electrode, a ground electrode, and a firing pad. The method may include the steps of: applying a first laser beam to attach the firing pad to the ground electrode, and then using a second laser beam from the same laser beam welder to attach the ground electrode to the metallic shell.
|Dual laser beam system used with an electron microscope and fib|
The present invention discloses an electron microscope and fib system for processing and imaging of a variety of materials using two separate laser beams of different characteristics. The first laser beam is used for large bulk material removal and deep trench etching of a workpiece.
|Particle manipulation system with cytometric confirmation|
A mems-based particle manipulation system which uses a particle manipulation stage and a plurality of laser interrogation regions. The laser interrogation regions may be used to assess the effectiveness or accuracy of the particle manipulation stage.
|Machine for making absorbent sanitary articles, such as nappies for babies or incontinence pads for adults, sanitary towels or the like|
In a machine for making absorbent sanitary articles, such as nappies for babies or incontinence pads for adults, sanitary towels or the like, a plurality of operating stations are equipped with cutting and/or sealing devices for the materials of which the articles (2) consist; all or some of the operating stations each being equipped with at least one laser unit for performing the cutting and/or sealing operation; the laser units all being connected to the same laser source (60).. .
|System for forming and modifying lenses and lenses formed thereby|
A lens for placement in a human eye, such as an intraocular lens, has at least some of its optical properties modified with a laser. The lens preferably contains at least 5% by weight uv absorber so commercially feasible rates of manufacture can be achieved.
