Optical Leader Delivers 8W Fiber Laser Pumps

MILPITAS, Calif., January 23, 2007 – JDSU, the leading enabler of broadband and optical innovation, announced today that it is showcasing a series of next generation high power diode lasers at Photonics West, the world’s largest optics and photonics event.  JDSU will display its products at Booth #927 on January 23 – 25, 2007 at the San Jose Convention Center in San Jose, California. 

Products at the event will include additions and enhancements to JDSU’s L3 series of fiber-coupled diode lasers, illustrating the company’s commitment to providing its customers with more powerful telecom-grade products at affordable industrial prices.   Products include the flagship 8 watt 6397-L3 diode laser that provides an unsurpassed combination of power, reliability and brightness for next generation fiber laser architectures.  For Neodymium (Nd)-doped solid state laser and medical systems, the 5 watt 2495-L3 Series provides a highly reliable, 808 nm fiber-coupled pump laser alternative.

“A transition is underway within the industrial laser industry towards highly reliable, telecom-grade diode pump lasers,” said Toby Strite, manager, High Power Laser Marketing at JDSU.  “The extensions we’ve made to our industry-leading L3 platform reinforces that JDSU is at the forefront of this trend.”

Diode lasers that JDSU will showcase at the event include:

• 6397-L3 Series High-Power 8 watts 9xx nm Fiber–Coupled Diode Laser.  This next generation single emitter laser diode delivers 8 watts from a 105 µm fiber at three wavelengths: 915 nm, 940 nm, and 975 nm.  Used for a variety of industrial and medical applications, the 6397-L3 laser extends JDSU’s industry leading fiber laser pump power by more than 20 percent.
• 2495-L3 Series 808 nm Fiber–Coupled Diode Laser provides the highest available 808 nm power at 5 watts from a 105 µm fiber.  Used for pumping Nd-doped solid state lasers and a variety of medical and dental applications, the 2495-L3 laser offers a highly reliable alternative to fiber-coupled diode laser arrays.
• 2486-L3 Series 830 nm Fiber-Coupled Diode Laser offers 2 watts from a 60 µm fiber into 0.2 Numerical Aperture (NA), ideal for photonics power and graphic arts applications.
• 6395-L3 Series 940 nm Fiber-Coupled Diode Laser offers 2.5 watts from a 50 µm fiber into 0.2 NA, ideal for graphic arts and materials processing applications.
• 5400 Series J-package extends JDSU’s 8xx nm single-mode diode laser portfolio into a reduced-cost, small form-factor package.  Used for a variety of graphic arts, night vision and spectroscopic applications, the J-package device is available at three wavelengths: 810 nm, 830 nm and 850 nm and two rated output powers: 50 mW and 100 mW.

In addition, JDSU diode laser experts are presenting two key papers during the show:

“High-Power, High-Efficiency Laser Diodes at JDSU.”  This presentation will take place on Monday, January 22 at 2:40 p.m. PST in SJCC Room J3.

“Very High Power 1330 nm InP Single Mode Distributed Feedback Laser Diode with Reduced Linewidth.”  This presentation will occur on Monday, January 22 at 3:40 p.m. PST in SJCC Room A5.
