Dilas has developed a high brightness, conduction-cooled fibre-coupled diode laser module based on diode laser bars that provides up to 40W output power from a 100µm fibre core at a wavelength of 976nm with a numerical aperture of <0.22.
The company claims test results showing a wall-plug efficiency of greater than 40 per cent at operating current. The electrically isolated single-bar package with a small footprint is a key feature in this product’s architecture, measuring 70 x 30 x 17mm.
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 ideally designed for a wide array of applications that range from fibre laser pumping to micro-materials processing to medical.
The laser will be released in Q3 of this year after going through Dilas’ release process to ensure quality and reliability.
