High-Power Chip Scale Coherent Laser Array

In the proposed effort, Clemson University COMSET, Corcoran Engineering, and Freedom Photonics will develop chip-scale directed energy microsystems using coherent beam combining of single mode lasers to provide a high-power output beam with excellent beam quality and high brightness.  To create this high--performance Photonic Integrated Circuit (PIC), we will design, fabricate and demonstrate a high-power laser array (0.9 – 2.1 micron wavelength) with diffraction-limited beam quality on an array of high-power NIR lasers all integrated onto a single monolithic chip using the patented FIRE technology.  Development of this compact laser source will enhance the performance of multiple DoD applications across a broad range of applications such as long range IRCM, laser communication, and any system that requires a compact laser with high power output and excellent beam quality.  This technology can be utilized to provide high power performance using a wide variety of laser systems at virtually any wavelength.
