Nufern introduces NuQ 20W fiber marking laser

Mon, 08 Sep 2008 00:00:00 -0800

Nufern, a leading manufacturer of active fibers, fiber lasers and amplifiers, will introduce its NuQ™ industrial pulsed fiber marking laser at the International Manufacturing Technology Show (IMTS) in Chicago this week.

The NuQ laser is a 20W average power, Q-switched fiber laser based on Nufern's optimized ytterbium-doped fiber. It features a fast turn-on time of 125 µs to maximize production throughput, and delivers high peak power from an industry standard OEM footprint. Nufern believes the NuQ laser will offer new and existing pulsed fiber laser customers, both OEM and job shops, an alternative credible supplier in the market with a proven track record of delivering fiber laser technology,” says Bryce Samson, VP of Business Development.

Featuring a Gaussian pulse shape and single-mode beam quality, the 20W NuQ laser delivers 1 mJ (10 kW peak power) pulses with more marking power per output watt than other lasers in its class. The laser offers a widely adjustable operating range of output power and pulse repetition rate, making it adaptable to a variety of marking, etching, engraving, and trimming applications. It emits zero bleed-through power when gated off to eliminate ghost lines between marks, even on sensitive materials.

The rugged, air cooled, monolithic architecture is pumped by highly reliable single emitter diode technology for extremely long life expectancy with no maintenance requirements. The laser comes complete with a 3m armored fiber delivery cable and precision optical isolator as standard. It is powered by a simple 24V universal power supply through an industry standard 24-pin interface, for simple drop-in replacement of existing systems.

Nufern releases polarization maintaining (PM) Gyroscope and Sensor fibers with reduced coating ...

Tue, 06 May 2008 00:00:00 -0800

Nufern, a leading U.S. manufacturer of fiber laser and amplifier modules and specialty optical fibers, announced today further expansion of their range of small form-factor polarization maintaining (PM) fibers.

With its numerous inherent advantages including manufacturing scalability and product uniformity PANDA-style PM fibers have long been the preferred technology for all telecommunication applications. However, the extreme birefringence and small form-factor requirements of gyroscope and fiber optic voltage and current sensor applications has long meant that such users have had to rely upon bow-tie or elliptical clad PM fibers. In 2006 Nufern released a suite of compositionally optimized PANDA-style fibers that have since allowed gyroscope manufacturers to take advantage of the many benefits inherent to the PANDA design technology without sacrificing other important attributes such as high birefringence and bend insensitivity which are critical for the manufacture of high precision, high-performance coils.

Nufern has now further expanded this product portfolio with the release of a suite of fibers with reduced coating diameters. By reducing the outer cladding diameters of these fibers from the conventional 165 micron to 125 micron without compromising birefringence or increasing bend-induced crosstalk, we are allowing customers to further substantially reduce the size of their gyroscope and sensor products, said Adrian Carter, Chief Technical Officer.

Nufern addresses the need for high efficiency Er/Yb double clad fiber for CATV amplifiers

Wed, 27 Feb 2008 00:00:00 -0800

Nufern, a leading U.S. manufacturer of specialty optical fibers and fiber laser and amplifier modules, announced today the introduction of a high efficiency Er/Yb double clad fiber for CATV amplifiers.

The new SM-EYDF-6/125-HE is a double clad fiber with a core composition designed for high conversion efficiency in high power amplifiers pumped at 915 to 960 nm. The high efficiency translates directly into high signal output power and reduced pump power requirements.

“CATV amplifier manufacturers have been asking for high efficiency Er/Yb fiber to help reduce their pump power requirements,” says Dr. Adrian Carter, CTO and Asia/Pacific Sales Director. “This double clad fiber addresses those needs for amplifiers utilizing 915 to 960 nm multimode pumps.”

The fiber is manufactured to exceptionally tight mechanical and optical tolerances. The resulting uniformity helps to ensure high yield when the fiber is used in device manufacturing. All Nufern fibers are produced under an ISO 9001:2000 certified quality management system.

Nufern also supplies a matched passive double clad version of this of this fiber as the ideal component and delivery fiber for use with its active counterpart.

Nufern introduces new Erbium/Ytterbium co-doped and Ytterbium-doped LMA fibers

Tue, 22 Jan 2008 00:00:00 -0800

Nufern, the largest independent manufacturer of fiber laser and amplifier modules and specialty optical fibers, exhibiting this week at Photonics West 2008, announced today further expansion of their NuPOWER™ line of active fibers.

The new fibers include an Erbium/Ytterbium co-doped (PM-EYDF-17/200) and Ytterbium-doped large mode area (LMA) fibers (PLMA-YDF-10/125 and PLMA-YDF-25/400). All three fibers are polarization maintaining (PM), double clad fibers and are complemented by the availability of matched passive fibers for component and pigtail development. The launch also includes a non-PM variant, LMA-YDF-10/130.

These new fibers further complement Nufern’s already extensive range of active and passive double clad fibers. “This expansion of Nufern’s standard product portfolio demonstrates our ongoing commitment to support the laser and amplifier industry with best-in-class fibers,” said Adrian Carter, Nufern’s Chief Technology Officer.
