The fibre-coupled, multi-bar modules deliver 300W through a cladding mode free QBH high-power, 200µm core diameter fibre, with a low numerical aperture of < 0.20 and WPE of > 35 per cent. Packaged in up to 10-bar configurations, these designs are based on industry standard conductively-cooled bars, which are optically stacked and polarisation-coupled. The product requires only industrial water for cooling.
Achieving high brightness and high efficiency, this new module has demonstrated a lifetime greater than 10,000 hours at 300W CW operating conditions.
Custom wavelengths are available upon request. These fibre-coupled, multi-bar modules are suitable for direct diode applications or fibre and solid-state laser pumping.
