Alfalight touts 6W pump diode laser for cable TV, FTTx amps

DECEMBER 8, 2008 -- Alfalight says its new 940-nm, 6W uncooled multimode laser diode is targeted at such telecom applications as erbium-ytterbium fiber amplifiers for CaTV and FTTx networks.

DECEMBER 8, 2008 -- Alfalight Inc. (search for Alfalight), supplier of high-power diode lasers, today announced the availability of the AM6-940B-20-608, a 940-nm, 6W uncooled multimode laser diode for cladding-pumped telecom fiber amplifiers. At pricing comparable to previous 4W devices, the new higher output diode improves dollar-per-watt performance by about 50%, claim company representatives.

"Alfalight has been delivering fully-qualified pump diodes for telecom applications since 2003," reports Ron Bechtold, vice president of sales and marketing at Alfalight. "With this latest 940-nm device, we continue to advance dollar-per-watt performance for high reliability laser diode pump solutions for telecommunications applications."

According to Alfalight, the AM6-940B-20-608 device includes a thermistor for temperature tracking, supporting complete system diagnostic and performance monitoring. It is available now in a compact, hermetic six-pin package and is offered with a 105-micron, 0.22 NA fiber.

Target telecom applications are erbium-ytterbium fiber amplifiers for CaTV and FTTx networks. The device is fully qualified and meets all GR-468 standards.
