Development of an efficient cw optical parametric oscillator with a triple-cavity differential-control configuration

光学参量振荡器作为可调谐的相干光源在各个领域都有很好的应用前景。然而，在连续波光参量振荡器中，很难获得阈值较低的稳定可调谐振荡。本研究采用三腔差分控制结构，研制了一种高效的周期极化KTP连续光参量振荡器(PpKTP)。从而以较低的阈值实现了连续波OPO的连续调谐。

Optical parametric oscillators are useful devices in various fields as the tunable coherent light sources. It is, however, difficult to obtain the stable tunable oscillation which has a low threshold in continuous-wave (cw) optical parametric oscillators. In this study, an efficient cw optical parametric oscillator with a periodically poled KTP (PPKTP) has been developed by using a triple-cavity differential-control configuration. Accordingly, the continuous tuning of the cw OPO has been achieved with a low threshold.
