MILPITAS, Calif., Aug. 13, 2007 -- JDSU announced today its has introduced an 2495-L3 series 808-nm fiber-coupled diode laser, incorporating new chip technology that makes it well-suited for many industrial, dental and medical applications. It generates twice as much power and the highest level of 808-nm brightness available among single-emitter fiber coupled diode lasers, the company said.

“As the diode laser industry has matured, JDSU has leveraged its expertise in the telecom space and applied it to the industrial sector, bringing higher performance and lower cost diode laser solutions to the market,” said Alex Schoenfelder, vice president and general manager of JDSU’s Integrated Photonics unit. “The 2495-L3 Series not only provides a more elegant offering for high-precision laser applications, it also opens the door for JDSU to participate in new markets.”

For industrial applications, the 2495-L3 diode laser optically pumps neodymium (Nd)-doped material to generate a 1064-nm output. The 1064-nm beam is used directly, or converted to green and ultraviolet (UV) laser light through harmonic conversion. These wavelengths are used for material-processing applications such as scribing or cutting semiconductor materials.

The 2495-L3 diode laser provides a brighter, more reliable optical pumping alternative to conventional multi-emitter (bar) diode lasers, JDSU said in a statement. "In a typical configuration, several 2495-L3 devices with 4W fiber output are bundled together to provide power equal to a conventional bar. This arrangement provides much higher power per single fiber, and the distributed architecture prevents a single point of failure compared to bar solutions."

The company said the new diode laser addresses a growing demand for the use of 808-nm diode lasers in the dental and medical fields. For example, Japan has certified this wavelength as the approved frequency for specific procedures.

"For soft-tissue dental processes, the 2495-L3 diode laser allows a dentist to more accurately treat diseased gum tissue without disturbing surrounding healthy tissue. In the therapeutic medical area of biostimulation, the 2495-L3 diode laser provides localized heat to stimulate damaged muscle tissue to relieve pain and discomfort," JDSU said.
