3S unveils 500mW 1064nm seed laser module for fiber lasers

At this week’s LASER World of Photonics 2009 event in Munich, Germany, 3S Photonics of Nozay, France, which manufactures laser chips, optical discrete modules and passive components for telecom networks, is launching what it claims is the industry’s most powerful CW and pulsed 1064nm cooled laser diode modules, to be used as seed lasers for fiber-laser applications.

Leveraging its technical expertise and its latest developments in the telecom area, 3S is releasing two enhanced versions of its 1064 CHP Series laser diode modules (with operating wavelengths of 1050-1070nm), capable of delivering up to 500mW CW of optical power at 1000mA through single-mode fiber and intended for industrial applications:

• a CW version, with high PER values;
• a Pulsed version, stabilized with a narrow-bandwidth fiber Bragg grating (FBG) in the polarization-maintaining single-mode fiber (PMF) pigtail.

The seed laser modules have been characterized at very high operating peak currents up to 1.7A with 1µs/500kHz pulses, and have proven their long-term reliability in pulsed-mode operation, says 3S. The low-profile hermetically sealed 14-pin butterfly package incorporates an ultra-high-power 1060nm single-mode laser diode including an internal thermo-electric cooler (TEC), a thermistor and an InGaAs back-facet monitor photodiode.

“These new modules provide more than 30% extra power compared with current offers as well as a telecom-grade reliability level,” says Yannick Bailly, VP of marketing & product management. “It represents a significant step forward for our customers involved in industrial laser markets, looking for increased output powers but also for more and more reliability,” he adds.

The new 1064 CHP modules have already proven their long-term reliability through a dedicated 4000 hour life-test with an injection current of 1.2A and a heat sink temperature of up to 50°C. Thermal cycling, high-temperature storage and mechanical integrity tests have also been passed, says the firm. The mean time to failure (MTTF) exceeds 100,000 hours.
