Miniature UV Sources for Imaging Applications

DARPA is interested in advanced UV laser technology for development of miniature UV 3D LIDARs. UV sources are preferred for seeing through many natural and man made obscurants. Princeton Optronics proposes to develop a miniature UV source at wavelength below 300nm by pumping a solid state laser gain medium with VCSEL array and frequency convert the laser beam to UV frequency. With this approach we propose to develop a very small laser that will fit inside a telecom butterfly package with a wide range of power output levels. In phase I, we have demonstrated the feasibility of the concept through theory and experiments. In phase II, we would develop a prototype which will be qualified and commercialized.
