The project CHARMING aims at developing compact and fully fibred visible lasers for fluorescencespectroscopy, high resolution confocal microscopy and tryptophan imaging. These applications requirepulsed operation (about 100 ps at repetition rates from 1 to 80 MHz), various wavelengths in the visible(from 515 to 630 nm typically) and in the UV (for tryptophan imaging), high average power (up to 500 ...
