Modulated Laser Beams
Modulated laser beams refer to the use of laser technology to transmit information by varying the amplitude, frequency, or phase of the laser beam. This technique is commonly used in space and astronautical engineering for communication purposes, as it allows for high-speed data transmission over long distances with high accuracy and reliability. Modulated laser beams are also used in various applications such as remote sensing, laser ranging, and laser spectroscopy. The modulation of the laser beam can be achieved through various methods such as direct modulation, external modulation, or mode locking.
