November 2, 2004 Berlin, Germany -- Lumics, manufacturer of pump laser modules and laser chips, has introduced the uncooled LU0975M040 laser module with up to 4-W output power from a multimode fiber.
The LU0975M040 is available in an uncooled, low profile, 14-pin butterfly package coupled with a 100/125-um multimode fiber with a numerical aperture of 0.22. The fiber is terminated with a standard 2.5-mm diameter ceramic ferrule. FC/PC or SMA connectors are optional.
Target applications include industrial fiber lasers and Erbium doped fiber amplifiers. The new generation of high power modules allows a cost effective system design with enhanced performance.
The complete module assembly is based on superior telecom laser package technology, say company representatives. The production is ISO 9001 approved with several screening steps throughout the chip manufacturing and module assembly process.
The operating current is specified with typically 6.5 A. The very low forward voltage is specified with max. 3.2 V, and 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.
