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 (1um, 1.55um, and 2um). In this SBIR program, we will develop an Er-doped fiber laser illuminator, generating well-tailored laser pulses at the eye-safe 1.55um with transform-limited linewidth and multiple-mJ of pulse energy at a rep rate of > 10kHz, which is not available on the market, but can be an enabling commercial solution to a variety of coherent LiDAR applications at a long standoff distance. This SBIR Phase II program will focus on demonstrating and prototyping such an all-fiber multi-mJ-energy coherent pulsed laser at 1.55um, which would benefit the DAF customers and our existing commercial customer – Lockheed Martin Corporation for a wide range of coherent LiDAR applications (see the support letters from Lockheed Martin Corporation).
