Latest Patents

Yuanshan Liu holds a patent for a method titled "Method for producing an externally injected gain switch laser ultrashort pulse." This method involves several steps, including the input of ultrashort light pulse signals with multi-longitudinal mode characteristics into an optical amplifier for amplification. A spectral component signal selector is used to select a narrow spectral component signal outputted by the optical amplifier. This signal is then utilized as an external seed light, which is reinjected into the gain switch laser through a spectral component signal feedback loop. This process enhances the oscillation of a selected single longitudinal mode within the cavity of the gain switch laser, leading to an externally light-injected locking mechanism.
