Beam Combination Boosts Power for Quantum Cascade Lasers

WebSep 21, 2024 · The beam combining efficiency is approximately equal to the external cavity efficiency of a single laser, which is expressed as the power ratio of the FP laser to the external cavity laser. For FP lasers and external cavity lasers, from laser lasing to saturation output, the output power and current are approximately linearly related to P = η ... WebThe simpler variant is incoherent combining. For example, the output beams of two broad area laser diodes, one being vertically polarized and the other one horizontally polarized, can be sent onto a thin-film polarizer such that one of the beams is reflected, the other one transmitted, and both beams then propagate in the same direction.
