Abstract :
Summary form only given. We report on a new way to construct an OPO with a harmonic repetition rate which is determined by the cavity length difference between the OPO and its pump laser. This method paves the way for the generation of a 10 GHz repetition-rate OPO. The use of a 1 GHz repetition-rate oscillator as a pump source may lead to a 10 GHz repetition- rate OPO by adjusting its cavity length so that the difference between the time intervals of the pulse trains of the OPO and the pump laser is 100 ps, which corresponds to a total cavity length of 270 mm or 330 mm for a ring-cavity OPO.
