Paper Abstract

Single mode with in-phase operation of the laser arrays is one of the main challenges for engineers to achieve high power in phase far field emission. Recently single mode lasing based on non-Hermitian engineering of the laser is investigated and two scenarios based on parity time (PT) symmetry and super symmetry are presented. Here we present a new method based on Q-enhancing to achieve single mode operation. This design device will satisfy requirement for LIDARs in space applications. The output supports up-to 300 Watts for few integrated coupled cavity lasers.
