Abstract
Dual wavelength laser energy in the low infrared electromagnetic spectrum destroys bacteria via photo-damage optical interactions through direct selective absorption of optical energy by intracellular bacterial chromophores. The dual wave length laser system includes an optical assembly including two distinct diode laser ranges (870 nm diode array and 930 nm diode array) that can be emitted to achieve maximal bacterial elimination.
