100 micron fibre-coupled diode lasers

ES Technology, the UK distributor for Dilas's range of diode laser components, has announced the development by Dilas 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 100µm fibre core, at a wavelength of 976nm and with a numerical aperture of <0.22. This new module will ensure high power, brightness and power efficiency. Wall-plug efficiency greater than 40 per cent at operating current has been achieved by Dilas during testing.

The electrically isolated single-bar package has a small footprint, which is a key feature in this product's architecture, measuring just 70 x 30 x 17mm. The laser power from this 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 well suited to a broad spectrum of applications ranging from fibre laser pumping to micro-materials processing and medical applications.
