An All-Fiber High-Energy Pulsed Illuminator for Coherent Imaging

Over the past several years, AdValue Photonics has developed a proprietary fiber laser technology, enabling >1mJ pulse energy generation of transform-limited-linewidth laser pulses from all-fiber-format robust laser systems at multiple wavelength bands (1µm, 1.55µm, and 2µm). In this SBIR program, we will develop an eye-safe all-fiber laser illuminator for coherent 3D imaging and vibration imaging, which will be able to emit well-tailored laser pulses of transform-limited linewidth with >1mJ of pulse energy at a rep rate of > 10kHz. At the end of this SBIR program, we’ll demonstrate an eye-safe all-fiber mJ-pulse-energy laser illuminator with a maximum average output power more than 20W.
