Nd:LiNbO/sub 3/ microchip laser with 20 GHz subcarrier

This paper reports on the development of a 20 GHz mode-locked Nd:LiNbO/sub 3/ microchip laser operating at 1.084 /spl mu/m with an output power greater than 35 mW (CW). With this configuration, a single device simultaneously generates the optical carrier and the microwave subcarrier. A modulation index of 96% was obtained for a driving microwave power of 12.6 dBm at 20 GHz. An information signal up to 8 GHz was also superimposed on the 20 GHz subcarrier using an external modulator.
