DILAS Is Now Delivering 40W of Output Power

Diode laser maker DILAS of Mainz, Germany is now delivering 40W of output power (substantially higher than previously available) from a T-bar-based 638nm 400-micron/0.22NA fiber-coupled module used for cinema projection.

DILAS says that, through optimization of the semiconductor chip structures and optical parameters, its tailored bar (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, says the firm.

The visible 638nm fiber-coupled T-bar offers advantages over conventional lamp-based technology, claims DILAS. In cinema projectors, higher efficiency, much smaller footprint, lower cost of ownership, higher reliability, and higher brightness are all enabled, it adds.

By extending the T-Bar-based scalable concept, more advanced modules will soon be made available to enable development and commercialization of high-power diode laser-based RGB projection laser systems, DILAS concludes.
