调谐信号 meaning in Chinese

harmonic ringing

The experimental results are fit well with theoretical calculation . 4 . reviewing different methods for constructing optical superlattice . parameters are designed for constructing ppln used for the second harmonic generation of 1064nm pumping wave
晶体，声光调q获得1064urn脉冲输出，泵浦多周期的ppln opo ，获得可调谐信号光输出，实验结果与理论计算相吻合。
