摘　　要：光纤光栅激光器以其增益高、频率啁啾效应小、抗电磁干扰,特别是可调谐的特点而被广泛关注。利用V-I传输矩阵法对光纤光栅激光器的模式特性进行了分析,从谱线间隔与谱线数目、光栅反射率对谱线深度的影响、单纵模输出条件及阈值腔长3个方面分析了光纤光栅谐振腔在不同特性参数下的模式特性,并与多层膜法的分析结果进行了比较,发现V-I传输矩阵法可以在保证分析精度的前提下提高运算效率。实验结果与理论分析结果基本一致。Due to its high gain,small frequency chirp,resistance electromagnetic disturbance and especially tuning,fiber grating laser has attracted a lot of interest.V-I transmission matrix method was presented firstly to analyze the mode characteristics of fiber grating laser at different parameters from three aspects： spectral lines interval and number,effect of grating reflectivity on spectral lines depth,condition of single longitudinal mode output and threshold cavity length.Compared with the multi-layer method,V-I transmission matrix method could save the calculation time apparently under the premise of ensuring analysis accuracy.The experimental results are basically consistent with the theoretical analysis results.
