Abstract :
Beat note stabilization of a 10-60 GHz dual polarization Nd:YAG microchip laser through optical down conversion is reported. The laser cavity consists of a Nd:YAG crystal glued to the LiTaO3 electro-optic crystal. The cavity mirrors are directly coated onto the external faces of the crystals. When pumped at 808 nm, this laser sustains the oscillation of two linearly polarized modes aligned with the LiTaO3 neutral axes. The frequency difference can be tuned up to 60 GHz, by the thermo-optic effect (3 GHz/K) and then finely tuned by the electro-optic effect (1 MHz/V). Beat note is stabilzed by implementing optoelectronic PLL.
