We present our activities on the development of narrow linewidth tunable optical parametric sources and their integration in gas sensing instruments. In particular, we have introduced the nested cavity optical parametric oscillator (NesCOPO) scheme that enables to implement very compact devices. The NesCOPO was successfully demonstrated in the microsecond to nanosecond regime and in spectral ranges from short- to long-wave infrared. Its high potential was demonstrated both for local photoacoustic spectroscopy and standoff detection using lidar instruments. We also present our recent advances on rapidly tunable picosecond OPOs based on aperiodic quasi-phase matching and their application to gas detection.
