The work fell under the HEL TD Phase I contract, awarded last year to design a beam control system for a truck-mounted laser weapon system.
The study, conducted by Nottingham and Loughborough University, in conjunction with fruit growers Berryworld, saw microbiologists work alongside a fruit supplier to try out the prototype plasma beam.
