NP Photonics has developed high power single frequency narrow linewidth 1550nm and 1064nm fiber laser products for LIDAR, sensing, and telecommunications. The fiber laser incorporates proprietary fiber technology developed at NP Photonics. Current state-of-art technologies have been developed primarily for terrestrial applications and can not provide all features of high reliability, high power, and radiation hardness at the same time to meet the requirements. We propose a high reliability, radiation hard, high wall plug efficiency, rugged, compact, 10W S-band tunable all fiber based transmitter covering 1450-1500nm by using highly thulium and terbium co-doped S-band tunable fiber laser, highly thulium and terbium co-doped tellurite fiber MOPA system and external modulation.
Benefit: The high power S-band tunable all fiber based transmitter proposed here has the potential to be widely used in satellite communications. It can be used for coherent communication for airborne LIDAR and Unmanned Aerial Vehicles. It will also provide a wide range of opportunities in undersea free communications, terrestrial-based communications, wavelength division multiplexed network, sensing, scientific instrumentation, and R&D.
