Research Overview:

The research activities focus on design/development/characterization of nonlinear frequency conversion/optical parametric oscillators/optical devices/optical materials, together with theoretical modelling and simulations. The realization and development of the coherent sources are based on optical parametric oscillators (OPOs), as well as second/third-harmonic generation (SHG/THG) and sum/difference-frequency generation (SFG/DFG) techniques, enabling access to unprecedented wavelength regions from the ultraviolet to the deep mid-infrared in all time-scale from continuous-wave to ultrafast. Various novel architectures/approaches and nonlinear materials are investigated. Further, fundamental studies in OPOs and optical nonlinear phenomena for the generation of optical frequency combs are carried on, with the aim of reducing the cost and complexity of existing sources, and finding many applications.

The different research topics of interest are:

• Experimental design/development/characterization of coherent light sources/optical devices based on nonlinear crystals in unprecedented wavelength regimes.

• Photo-physical response and investigation of various nonlinear materials.

• Frequency Combs- Fundamental studies in optical parametric oscillators for the generation of optical frequency combs for medical applications.
