Large Arrays of Microlasers For Far and Near-Field Imaging and Lidar in the Infrared, Visible, and Ultraviolet

Abstract

This AFOSR grant, initiated by Dr. Gernot S. Pomrenke in 2019, has been dedicated to the development of microlaser cavities for the pursuit of optical imaging systems and LIDAR which was first demonstrated under Grant No. FA9550-14-1-0002. We are pleased to report to AFOSR that the past three years of research have proven to be quite productive, yielding several developments that appear to be of significant value to the Air Force. Highlights of this research program include: The conception and development of a laser whose output comprises literally thousands of microlaser beams using Ti:Al2O3 as the gain media. In the far field, these beams combine to form a single beam of low coherence and virtually no speckle. Such a laser has been pursued for decades by the optical community and is ideal for high spatial and temporal resolution LIDAR. Speckle-free imaging at long distances, of moving objects, and of biological species. Fractal Lasers.
