Drop-in Replacement Carbon Dioxide Optics for Etching Lasers

A full line of OEM-quality drop-in replacement CO2 optics for lasers used in etching monuments, signs and other stone products is available from Laser Research Optics. Laser Research CO2 optics for popular monument and sign etching lasers are available in 0.75” and 1.5” dia. sizes and feature 4” to 7.5” focal lengths to provide deeper cuts.

MOPA Fiber Laser Source

Trotec is offering the MOPA fiber laser source as an option for its SpeedMarker galvo laser marking systems. MOPA technology opens up a new world of possibilities for marking metals and plastics because it allows the user to select pulse durations (between 4 and 200 ns), which provides a much wider range of laser parameters, more options for creating high-contrast, homogeneous markings, and the ability to mark colors on some metals.

Fiber to Fiber Coupler

A new Fiber to Fiber Coupler (FFC) from Coherent (formerly Optoskand AB) enables the use of replaceable, process fiber optic cables so that integral components of the fiber laser – most notably the feeding fiber – are not exposed to opto-mechanical damage, even in harsh industrial processes. Damage to the feeding fiber means long and often costly down time. But the new FFC enables the use of a separate fiber interface, and this separate delivery fiber can be exchanged in minutes in the case of damage.

RQB Fiber Optic Cables

Coherent (formerly Optoskand AB) has introduced RQB Fiber Optic Cables – new air-cooled, beam delivery, fiber optic cables with a standard QBH interface, for use with fiber lasers operating at CW power levels up to 1.5 kW (and pulsed lasers as high as 1 MW). This makes these new cables an attractive option for cost sensitive applications level, and also enhances system simplicity when utilized with air-cooled fiber lasers.

AVIA LX 355-20 Q-switched, Diode-pumped Solid-state Laser

Coherent says the AVIA LX 355-20 is an economical new q-switched, diode-pumped solid-state (DPSS) laser offering substantially longer operating lifetime than competitive products at similar power levels. The AVIA LX 355-20 delivers 20 W (at 50 kHz repetition rate) at 355 nm, a diffraction limited (M² <1.3) beam, and an expected lifetime of 20,000 hours.

Jenoptik opens new North America technology campus

On June 15, officials from the Jenoptik board of directors, the city of Rochester Hills, Mich., Oakland County and the state of Michigan, gathered at the company’s new facility in Rochester Hills to mark the grand opening. The building covers 100,000 sq. ft. on a 16-acre campus. Half of that acreage will be devoted to the production of laser cutting systems and automated gaging solutions for the automotive industry in North America.
