BERLIN, July 14 -- Lumics, a manufacturer of pump laser modules and laser chips, has introduced its LU0975M004 laser module with up to 4W output power from a multimode fiber.

Lumics offers the laser in a cooled, low-profile 14-pin butterfly package coupled with a 100/125-µm multimode fiber with a numerical aperture of 0.22. The fiber is terminated with a standard 2.5-mm-diameter ceramic ferrule.
   The target applications include analytical, medical applications and industrial fiber lasers and double-clad erbium-doped fiber amplifiers (EDFAs). The new generation of high-power modules allow a cost-effective system design with enhanced performance.

The complete module assembly is based on superior telecom laser package technology according to Telcordia reliability requirements. The production is manufactured in an ISO 9001-approved factory, with several screening steps throughout the chip manufacturing and module assembly process.   

The operating current is specified with typically 6.5A. The very low forward voltage is specified with max. 3.2V. The LU075M004 includes a thermo electric cooler, which is specified with maximum current of 3.5A and maximum 1.5 voltage. The threshold current is typically 245 mA. The performance of the device is based on Lumics' propriety chip technology, which ensures very high reliability with a breakthrough in laser facet passivation.

Products samples are available.

Visit Lumics at the ECOC optical communication conference and exhibition, to be held Sept. 6-9 in Stockholm, at the Laser2000 booth (269).
