Fruit-Enhanced Resistance to Microbial Infection Induced by Selective Laser Excitation

Grapes laser irradiation set-up. Individual grapes over an external crown of a disc of 30 cm diameter. Irradiation was provided through a dye laser (Continuum ND60), which was used to pump an INRAD-AT-III-UV frequency-doubling unit whose (BBO-TST) crystal allows scanning the output from 235 nm to 365 nm.
