| Abstract: | Cluster hopping effects and frequency instabilities prevent a wide use of doubly-resonant optical parametric oscillators (DROPOs) in the field of optical diagnostics, especially in the nanosecond regime. By using a two-cavity device, we demonstrate here that stable single-mode output can be obtained, provided that the length of each cavity is carefully chosen. |
