Mainz, Germany - Diode laser maker DILAS has delivered its 20,000th high-power, high-brightness, tailored bar-based (T-Bar) fiber laser pump module. Shipping its first unit in 2009, this product was designed and developed as a pump source for kilowatt-class fiber laser systems.

Planned as a volume product from the very beginning, the production process has a high degree of automation. Through the optimization of semiconductor chip structures and optical parameters, the company's T-Bar architecture delivers high beam quality and high power using standard micro-optic fast-axis collimators (FAC) and slow-axis collimators (SAC), all assembled with automated processes. The T-Bar is a monolithic multi-emitter source allowing the handling of multiple emitters during each manufacturing step, to lower complexity and ease manufacturing. The result is enhanced reproducibility, beam quality, and fiber-coupling efficiency.

Conservatively specified to 135W out of 200 µm, NA 0.22 when designed, the T-Bar module was later increased to 200 W out of 200 µm by optimizing the chip structures and fiber coupling processes. Today, the latest generation version has a higher density of tailored diode laser bars with an output power at 250 W out of 200 µm, and 270 W out of 225 µm. Whereas the fiber connector was intentionally detachable in the early phase, it turned out that the diode laser module is no longer considered a spare part. The latest generation is delivered with a non-detachable pigtailed fiber.

Within the tailored bar platform series, the company offers a number of other pump modules in different wavelengths and power. For more information, please visit www.dilas.com.
