ES Introduces Fibre-Coupled Diode-Laser Module

ES Technology, distributor for the range of Dilas diode-laser components, has announced the development of a high-brightness, conduction-cooled, fibre-coupled diode-laser module. This latest development is based on diode-laser bars that provide up to 40W output power from a 100-micron fibre core at a wavelength of 976nm and with a numerical aperture of 0.22.

The new module will ensure high power, brightness and power efficiency, with wall-plug efficiency of greater than 40 per cent of operating current being achieved by Dilas during testing. The electrically isolated single-bar package has a small footprint, measuring 70mm in length, 30mm in width and 17mm in height. The laser power from the fibre-coupled module is delivered via a non-detachable fibre core, which is terminated with a standard SMA 905 connector or cleaved fibre end. With excellent heat removal by direct thermal contact, this industrial package is suitable for a variety of applications, ranging from fibre laser pumping to micro-materials processing and medical.

The module will be officially released in the third quarter of 2010; however, it is currently available by special order. In addition to the distribution of Dilas laser products and other electro-optic components, ES Technology also provides subcontract laser-marking services, after-sales services and parts, sales and service for ULS flatbed CO2 lasers and the design and manufacture of laser-marking systems. The company is also the UK and Ireland distributor for Concept Laser and its range of Lasercusing systems.
