A compact and electric tuning microwave source based on a diode-pumped composite Nd:YAG-LiNbO(3) cavity microchip laser is demonstrated. The electro-optical element introduces an electric tuning intra-cavity birefringence which causes a tunable frequency difference between two spilt orthogonal polarization states of a longitude mode. Thus a continuously tunable microwave signal with frequency up to 14.12 GHz can be easily generated by beating the two polarization modes on a high speed photodetector.
展示了一种基于二极管泵浦复合Nd:YAG-LiNbO(3)腔微芯片激光器的紧凑型电调谐微波源。电光元件引入了电调谐腔内双折射，这导致纵向模式的两个分离正交偏振态之间产生可调频率差。因此，通过在高速光电探测器上使两个偏振模式拍频，可以轻松产生频率高达14.12 GHz的连续可调微波信号。
