Researchers Generate Laser Pulses at a Higher Repetition Rate Written by AZoOpticsJan 20 2021 Pulsed lasers tend to emit light repeatedly for a short period as if they blink. They can focus more energy compared to a continuous wave laser, whose intensity remains unaltered over time. Abstract illustration. Image Credit: Korea Institute of Science and Technology. Loading of digital signals in a pulsed laser enables each pulse to encode one bit of data. In this case, the repetition rate is directl...

Credit: Korea Institute of Science and Technology(KIST) Pulsed lasers repeatedly emit light for a short period of time as if blinking. They have the advantage of focusing more energy than a continuous wave laser, whose intensity is kept unchanged over time. If digital signals are loaded in a pulsed laser, each pulse can encode one bit of data. In this respect, the higher the repetition rate, the more the amount of data that can be transmitted. However, conventional optical-fiber-based pulsed la...
