The combination of multiphoton, CARS and STED microscopy as powerful imaging techniques in medical devices with multimodal functionalities is a major technical and economic challenge, as these techniques are based on different excitation lasers. In the CARMEN project, a novel multimodal imaging system with multiphoton functionality and super resolution is being developed, which can be used for histological analysis of e.g. biological tissue. The new imaging system combines the possibilities of multiphoton microscopy, CARS and super-resolution STED microscopy in a single device. These diverse capabilities can only be achieved by a specially developed, innovative ultra-short pulse laser system with dual wavelength output based on fiber laser-pumped, rapidly tunable OPOs generating synchronized femtosecond and picosecond pulses.

The project is conducted in cooperation with JenLab GmbH (, Deltatec s.a. (, Laserspec ( and Multitel ASBL (
