Abstract
The ability to combine incoherent sources with attractive performances enable hardware integration issues to be resolved using stable, good quality off-the-shelf components. Some new generation imaging systems can be found in the mid-infrared (MIR). The most portable laser technology at this range, our Quantum Cascade Laser source can provide light power of around 2 W, industrial grade. With the Multi-plane Light Conversion technique and a modal approach, we present non-coherent beam combiner for QCL with optimal beam quality, demonstrating the state of the art in terms of M2.
