Oclaro’s 808nm High Performance LDs are Very Efficient
The firm’s new GaAs based laser diodes (LDs) are suited to solid state laser pumping, direct diode applications and medical markets and will be exhibited at Photonics West 2011 in San Francisco through January 22 - 27, 2011.
Oclaro, a provider of optical communications and laser solutions has a new line of laser diodes that the company says feature the highest level of efficiency and performance in the industry.
Combining laser diode technology from Oclaro's Zurich facility with the packaging technology from Oclaro's Tucson site, this new line of laser diodes, is being showcased at Photonics West in California next week.
These are Oclaro's first laser diodes to ship in volume for products originally developed in Tucson, including the collimated bar series and Prosario Series. Primarily used for diode pumped solid state lasers and direct medical applications, these new integrated platforms provide end-users and integrators another level of performance with a more compact size, more efficient thermal management and increased power.
"We are proud to see our integration efforts delivering the excellent results we anticipated," said Yves Le Maitre, Executive VP and Division Manager at Oclaro. "These new laser diodes demonstrate how we can take advantage of Oclaro's economies of scale and expertise to deliver the highest level of cost savings, operations efficiencies and manufacturing excellence − and then leverage the resulting technology across multiple Oclaro product lines."
Targeted at solid state laser pumping, direct diode applications and medical markets, Oclaro's new line of 60W 27%FF (Fill Factor) bars and 80W 50%FF bars are developed for CW (Continuous Wave) operation on a conductive heat-sink. The 60W and 80W diode bars offer leading brightness and power on an industry standard CS type assembly, which is fully compatible to previously released products. The increased brightness of the 60W product makes it most suitable for beam shaping and fiber coupling applications, while the 80W product excels in pumping applications and line sources.
These laser diode bars represent the first Oclaro E2 facet passivated and hard-soldered bars to be incorporated in the company’s collimated bar series and fiber coupled Prosario series. By integrating this technology into these two series, Oclaro can improve their output power, efficiency and reliability in order to offer customers a higher performing solution. This is another example of how Oclaro is taking its core technology and leveraging it across multiple product lines and markets.
The new high-powered laser products feature the Oclaro E2 mirror passivation process which protects the front facet of the bar against catastrophic optical mirror damage. In addition, the telecom grade AuSn (gold tin) hard solder makes the product suitable for industrial and defense applications in CW and hard-pulse operation mode. These two innovative manufacturing technologies significantly extend the life of Oclaro products by providing the highest level of reliability and robustness even in the most demanding applications.
In addition to showcasing its new high power laser diodes at Photonics West (Booth # 1001), Oclaro will be presenting six technical papers at associated symposia BIOS and LASE 2011.
