Incoherent combining and beam shaping in the Mid InfraRed range

Cailabs’ expertise in light shaping technology extends to the Mid InfraRed (MIR) spectrum, playing a crucial role in Directional Infrared Counter Measures (DIRCM). DIRCM uses a laser source to either blind or destroy the photoreceptive components of self-guided missiles, protecting aircraft, including helicopters, from this type of attack. To be effective, the laser source must emit light within the operating wavelength spectrum of the targeted optronic system’s photosensitive component, typically around 4 to 5 µm. Cailabs offers an innovative solution by combining Quantum Cascade Lasers (QCL). However, despite their ease of integration, QCL are currently limited to a few Watts in power. To address this, Cailabs has designed a module that enables the efficient incoherent combining of QCL outputs, generating a powerful combined beam with minimal divergence to effectively neutralize the thermal guidance mechanisms of missiles. Cailabs also offers beam shaping solutions for active imaging systems. This technology ensures uniform illumination of a specific area, facilitating a homogeneous backscatter signal intensity across the entire region of the receiver (photodiode array or camera).
