单频调制的相位调制激光在频率损失下激发的幅频效应
Amplitude-frequency effect excited by the phase-modulated laser with single-frequency modulation under frequency loss
摘要
Abstract
Given that the current research on amplitude-frequency effects is primarily limited to focusing on pulse top modulation from a time-domain perspective,which fails to comprehensively reveal its characteristics in the frequency domain or other dimen-sions,this study commences from a single-frequency laser phase modulation model,combining theoretical simulations and exper-imental verifications.It investigates the impact of single-order frequency loss,overall frequency loss,and modulation depth changes on the excitation of amplitude-frequency effects,considering factors such as waveform intensity modulation,excited am-plitude modulation signal strength,and spectrum distribution changes.The research results indicate that as the phase-modulated laser deviates further from the center position of the filter,the waveform intensity modulation increases accordingly,while the ex-cited modulation signal strength exhibits a trend of first rising and then falling.Compared with single-order frequency loss,the amplitude-frequency effects excited by overall frequency loss mainly concentrate on the fundamental frequency and second har-monic.Additionally,an increase in modulation depth leads to an enhancement in spectral width and an intensification of the ex-cited modulation signal strength.关键词
