Laser machining method and apparatus

A method of delivering a beam of laser-radiation to a workpiece for processing the workpiece comprises transmitting the beam twice through an acousto-optic modulator (AOM) crystal in opposite zero-order directions of the AOM at separate locations on the AOM crystal, before delivering the beam to the workpiece.... Coherent Inc

Mechanically isolated optically pumped semiconductor laser

A housing for an optically pumped semiconductor (OPS) laser resonator is terminated at one end thereof by an OPS-chip. The laser resonator is assembled on a platform with the OPS-chip at one end of the platform. The platform is fixedly attached to a baseplate at the OPS-chip end of the... Coherent Inc

Achromatic anastigmatic anamorphic objective

In a flow cytometer, an objective lens for focusing an input laser-radiation beam including at least four different laser-radiation wavelengths in a common plane includes only three singlet lens-elements. Two of the elements are cylindrical elements arranged as a cylindrical telescope for shaping and reducing the size of the input... Coherent Inc

Exchangeable pump module

A modular solid-state laser comprises a diode-laser pump module and a laser-enclosure. The diode-laser pump module produces a collimated beam of laser-radiation for pumping a gain-element within the laser-enclosure. The beam of pump laser-radiation is focused into the gain-element by optics located within the laser-enclosure. The diode-laser pump module can... Coherent Inc

Stackable electrically-isolated diode-laser bar assembly

A diode-laser bar assembly comprises a diode-laser bar mounted onto a cooler by way of an electrically-insulating submount. A laminated connector is provided that includes two electrically-conducting sheets bonded to opposite sides on an electrically-insulating sheet. An electrical insulator is located between the laminated connector and the cooler. One electrically-conducting... Coherent Inc

Method and laser-cutting of transparent materials

A method for cutting a transparent brittle material using pulsed laser-radiation is disclosed. A beam of pulsed laser-radiation having an optical-axis is focused in the material by a variable-focus lens or mirror. The focus is translated along the optical-axis while the material is moved with respect to the beam to... Coherent Inc

Cooling diode-laser bars

A cooler for diode-laser bars comprises a machined base including a water-input plenum and a water-output plenum, and a top plate on which the diode-laser bars can be mounted. A stack of three etched plates is provided between the base and first plate. The stack of etched plates is configured... Coherent Inc

Aberration compensated diode-laser stack

Optical output beams from a vertical stack of diode-laser bars are focused by a simple focusing lens on an optical axis of the lens. The optical output beams from outlying diode-laser bars in the vertical stack are tilted with respect to the optical axis of the focusing lens such that... Coherent Inc

Enclosure for modified optical fiber

A mode-stripper for an optical fiber includes a water-cooled enclosure. A portion of an optical fiber to be mode-stripped is modified in a way which allows radiation to leak from cladding of the fiber. The optical fiber extends through the enclosure from a proximal end thereof to a distal end... Coherent Inc

Stackable electrically-isolated diode-laser bar assembly

A diode-laser assembly having an electrically isolated diode-laser bar on a cooled base-element is disclosed. The diode-laser bar is electrically isolated from the base-element and electrically isolated from any coolant water, thereby eliminating the need for de-ionized water and mitigating corrosion due to galvanic action. Multiple such diode-laser assemblies are... Coherent Inc

Pulse-dividing a pulsed carbon monoxide laser

Laser-drilling apparatus includes a gas-discharge for laser emitting laser-radiation pulses, and two acousto-optic modulators (AOMs). The laser radiation pulses are characterized as having two temporal central portions between temporal leading and trailing edge portions. The AOMs are arranged to spatially separate the central temporal portions of the pulses from each... Coherent Inc

Cutting of brittle materials with tailored edge shape and roughness

The method of and device for cutting brittle materials with tailored edge shape and roughness are disclosed. The methods can include directing one or more tools to a portion of brittle material causing separation of the material into two or more portions, where the as-cut edge has a predetermined and... Coherent Inc

Fiber-laser pumped crystal-laser

An apparatus for generating and amplifying laser beams at approximately 1 micrometer wavelength is disclosed. The apparatus includes an ytterbium-doped gain-crystal pumped by an ytterbium fiber-laser. The fiber-laser enables a pump wavelength to be selected that minimizes heating of the gain-crystal. The apparatus can be configured for generating and amplifying... Coherent Inc

Carbon monoxide laser machining system

Laser-machining apparatus includes a carbon monoxide (CO) laser emitting a beam of laser-radiation having forty-four different wavelength components and optical elements for delivering the radiation to workpiece. An acousto-optic modulator is provided for modulating the beam on the workpiece. A birefringent plate is provided in the beam transported to the... Coherent Inc
