WebMOPA QCL difficult. Furthermore, the MOPA devices require separate electrical contacts for the seed and amplifier sections. Tapered lasers are a different approach in which the laser oscillation takes place in the combined tapered and seed sections and require only a single top contact. A short ridge waveguide section is followed by a tapered ... WebJan 1, 2024 · High-power QCLs are grown as a slab waveguide, with the laser core (the source of gain) acting as a guiding layer surrounded by bulk material acting as cladding. The creation of the ridge defining the width of the laser core requires the removal of material from the slab-grown waveguide through etching.
