Project Description

Following on from Nano-Tera Phase I project MIXSEL, we want to exploit our scientific leadership and consolidate our research efforts for real application demonstrations. We will continue to improve the VECSEL and MIXSEL sources towards prototype demonstrators for end-user demonstration in biomedical imaging, compact efficient white light generation for general high brightness illumination and frequency metrology applications. End-user demonstration will take place with our newly added university and industrial partners.
