LaserSharp introduces three-wavelength 14xx Raman gain units with controllable power for each wavelength

LaserSharp Corp. has launched its GainStar product line, a series of low-cost Raman gain modules with unmatched power efficiency to serve the WDM long haul, ultra-long haul, festooning, submarine, and metro core markets, explains the company. The RGM310 module is a 1000 mW, three-wavelength,14xx Raman fiber laser with independently controllable power for each wavelength.

LaserSharp will have a live demonstration of its GainStar product line at Booth #601 in Hall E during the OFC Conference in Anaheim, CA, from March 19 to 21, 2002.

GainStar Raman gain modules, which use a single, high-power Raman fiber laser to generate multiple wavelengths, are available in two models: the two- and three-wavelength RGM210 and RGM310 modules. They both use LaserSharp's proprietary fiber-laser technology.

The power in each wavelength is independently adjustable, from 20 to 80 percent of the 1000-mW total output power. This enables it to spectrally match the Raman gain profile to existing systems, eliminating the need for dynamic gain-flattening filters. Additionally, the all-fiber design with no free-space optics, combined with the use of redundant telecom-grade 915-nm multimode pump diodes, results in exceptional reliability, say company representatives.
