Illustration Fibre laser

MULTITEL has a strong experience in fire lasers development, going from Ultrashort to CW sources and covering a large spectral range (Vis, NIR, Mid-IR). The Applied Photonics department can help you developing the right fibre laser source for your application needs. Our lasers are currently used in various sectors like medical imaging, micromachining, sensing…

Our laser solutions

Multitel develops different type of laser sources based on fibre optical technology. Such laser sources exhibit high reliability, compactness, excellent beam quality and efficiency. For some applications we combine out fibre laser technology with other free-space amplification systems for reaching high energy. In all cases, our sources exhibit high beam quality and pointing stability.
