JDSU launches most powerful fiber-coupled diode laser

Broadband and optical communications component maker JDSU of Milpitas, CA, USA has launched what it claims is the most powerful fiber-coupled diode laser, its next-generation L4 platform.

The new telecom-grade L4 Series uses an innovative chip design to generate 10W of output power. Also, its package takes up less space compared to previous designs, enabling original equipment manufacturers (OEMs) to pack more diode lasers into a smaller space within a system.

The diode lasers are designed for use in a broad range of industrial, medical and dental applications, including fiber laser pumping, material processing, and dental soft-tissue surgery. 

“With the new L4 platform, JDSU has increased the performance, power and efficiency of our diode lasers, all within a smaller footprint,” says Alex Schoenfelder, VP and general manager of Integrated Photonics. “Our customers benefit by getting higher-performance diode laser solutions that aren’t more expensive than previous offerings, thanks to our high-volume manufacturing capabilities.”

New features of the L4 platform include:

  • Expanded fiber delivery options.(highest power available in the industry, at 10W, with a package that has the potential for future scalability; 100µm fiber delivery at either 0.22 or 0.15 numerical aperture (NA), allowing higher brightness in the fiber, or focusing in a smaller diameter for specific applications);
  • Smaller, more efficient package (taking up less space compared to previous designs and allowing more units to be packed within a smaller area);
  • New electrical format (a simplified electrical design removes the need for additional parts, easing integration into OEM systems);
  • Improved wavelength flexibility (available at 910–980nm).

JDSU will display the new platform at the SPIE Photonics West 2008 event at the San Jose Convention Center, CA (22 –24 January).
