Fibre-coupled diode laser pump module
Dilas has introduced a fibre-coupled diode laser pump module, developed for fibre laser pumping with kilohertz modulation capabilities.
The fibre-coupled pump module is based on a single-emitter platform in a sealed housing. It offers up to 30W laser power from a 105μm pigtailed fibre into a 0.15 numerical aperture at 915nm or 976nm (with optional wavelength stabilisation from 976nm-VBG).
The laser pump module’s low height and rugged architecture make it ideal for applications requiring fibre-combined pump power with kilohertz modulation capabilities, fostered by the serial connection of the multiple single emitters inside and its low operating current maximum of 12A.
Developed for ytterbium fibre laser pumping applications, the module is equipped with a filter to protect against back-propagating light at greater than 1μm. The module is also suitable for medical or materials processing applications that require a small fibre core diameter or low numerical aperture in a small footprint.
