Real-time reproduction of mode-locked pulse generation via high-speed spectrum matching algorithm

We propose a novel approach for the automated reproduction process of mode-locked pulse generation in a fiber laser, employing a statistical correlation analysis algorithm to execute rapid spectrum searching and matching. Our system incorporates a servo-based automatic control strategy to realize precise reconstruction of specific mode-locked states from white noise in accordance with desired spectral characteristics. The average reproduction time is 70 ms for a similarity, defined by the percentage error between targeted and matched spectra, of 98.96%. Consequently, our real-time reproduction algorithm offers a highly promising method for the automated manipulation of mode-locked pulse generation in laser industry.
