Paper Abstract

Quantum 2.0 applications such as gravitational sensing require narrow linewidth lasers at specific wavelength and significant optical power. For single photon lidar applications such as to image through scattering media, intense yet short optical pulses are required. These are requirements not readily provided by existing laser systems. We suggest the use of master oscillator power amplifier (MOPA) systems consisting of a seed source providing the required spectral and temporal optical characteristics combined with a semiconductor based tapered amplifier to amplify the seed power to levels adequate for the required quantum applications. Considerations of the construction of such systems are discussed. Furthermore, there operational specifications will be determined and the suitability for quantum applications will be discussed.
