General description:
4000 Series Pumps. High power, high reliability multimode pump modules

JDS Uniphase pump modules are fast becoming the standard for high power with high reliability in Erbium doped fiber amplifiers used for telecommunications applications. In order to address the growing market for pumping Ytterbium doped double-clad fiber lasers, JDS Uniphase has introduced the 4000 Series of high power 915 nm and 970 nm high reliability pump modules. These high power multimode pumps are qualified under the same rigorous Telcordia™ guidelines as our single-mode pumps.

Cladding pumped fiber laser coupling allows the use of multimode diode lasers which can reach higher powers than currently attainable in single mode diode lasers. The multimode laser diode used in this module has been characterized for reliable operation through the use of accelerated multi-cell lifetesting. The 4000 Series features 750mW at .22 NA and .15 NA from a 100 um multimode fiber.

Key Features
• Highly reliable 750 mW from a 100 um fiber
• 915 and 970 nm wavelengths
• .22 and .15 NA fiber output
• Demonstrated reliability through telecom qualification and life testing

Applications
• Ideal for pumping double-clad Ytterbium doped fiber lasers used in Raman amplification
• Ideal for pumping double-clad fiber amplifiers
