  • Optical Amplification Devices

    Optical Amplification Devices

    An optical amplifier is a device which receives some input signal light and generates an output signal with higher optical power. Typically, inputs and outputs are laser beams (very rarely other types of light beams), either propagating as Gaussian beams in free space or in a fiber. The. Optical amplifiers are used to create laser guide stars which provide feedback to the adaptive optics control systems which dynamically adjust the shape of the mirrors in the largest astronomical telescopes. This means that over a distance of 100km, a signal can lose around 20dB. The input light is amplified as it passes through a gain medium. When the gain medium is externally pumped (electrically or optically), a population inversion between. Optical amplifiers are a key component in modern optical communication and networking systems.


  • The role of active optical devices

    The role of active optical devices

    Active optics is a used with developed in the 1980s, which actively shapes a telescope's to prevent deformation due to external influences such as wind, temperature, and mechanical stress. Without active optics, the construction of 8 metre class telescopes is not possible, nor would telescopes with segmented mirrors be feasible.
