Alfalight launches 6W uncooled 940nm pump laser for CaTV and FTTx amplifiers

Alfalight Inc of Madison, WI, USA, which manufactures high-power diode lasers for industrial, defense and telecoms markets, has made available the AM6-940B-20-608, a 6W, 940nm uncooled multimode laser diode for cladding-pumped telecom fiber amplifiers (e.g. erbium-ytterbium fiber amplifiers for CaTV and FTTx networks).

The AM6-940B-20-608 includes an on-board thermistor for temperature tracking, supporting complete system diagnostic and performance monitoring. It is available in a compact, hermetic 6-pin package and is offered with a 105 micron, 0.22 NA fiber. The device is fully qualified and meets all GR-468 standards.

At pricing comparable to previous 4W devices, the new higher-output diode improves dollar-per-watt performance by about 50%, claims the firm.

“Alfalight has been delivering fully qualified pump diodes for telecom applications since 2003,” says Ron Bechtold, VP of sales & marketing. “With this latest 940nm device we continue to advance dollar-per-watt performance for high-reliability laser diode pump solutions for telecommunications applications,” he adds. Pricing is $450 each in quantities of 10 plus.
