JDSU, a provider of high precision optical solutions for industrial applications, announced the availability of a laser architecture that promises to deliver high precision solutions for industrial and commercial applications.

The new Industrial Diode Laser System (IDL) incorporates multiple single-emitter diodes combined into a single output fiber, and provides up to 100W of power. According to JDSU, single-emitter diodes offer the advantage of being pulsed on and off without affecting lifetime, unlike non-telecom grade bar diodes which have been the industry norm until now. While pulsing does not affect telecom-grade diode lifetime, it can dramatically reduce bar diode lifetimes. Using multiple devices allows for redundancy and improves thermal management.

"Historically, pulsing has resulted in a dramatic reduction of lifetime. This has proven not to be the case with telecom grade diodes," said Phillip Meredith, VP of JDSU's commercial laser products group. "The telecom industry presents far harsher environmental requirements than the commercial market. Therefore, leveraging JDSU's telecom expertise gives us an advantage in developing innovative laser solutions for the industrial and commercial laser market."

The press release from JDSU further said that competing 100W systems rely on as many as 19 output fibers, resulting in a lack of beam uniformity; whereas the IDL's single output fiber offers unprecedented beam quality. The 100W version is expected to enable plastic welding of components with high glass content, parts with low absorption, and/or allow for greater production throughput, added the company.
