中文摘要：

提出了一种用于光生mm波的单纵模双波长微片激光器。理论分析和实验研究了微片激光器单纵模双波长产生的机理。实验结果表明，当输入抽运电流为12A时，激光器输出的中心波长分别为1064．18nm和1064．50nm，波长间隔为0．32nm，对应的频差近似为85GHz；每个频率峰的-3dB谱宽为0．05nm，消光比大于22dB；通过偏振片对双波长偏振平行度进行检测，偏振平行度优于98％。

英文摘要：

A single-longitudinal-mode dual-frequency microchip laser for photonic generation of millimeter-wave signal is investigated. The single-longitudinal-mode duabfrequency resonance mechanism is studied theoretically. The experimental results show that with 12 A pumping current, the central wave- lengths of microchip laser are 1064.18 nm and 1064.50 nm,respectively. The space between two wave- lengths is 0. 32 nm,corresponding to 85 GHz. The --3 dB spectrum width of each peak is 0.05 nm,and the extinction ratio is above 22 dB. the polarizations of two wavelengths are nearly parallel.
