Abstract
A wavelength multiplexed holographic system includes a wavelength tunable blue-violet laser and a controller for wavelength multiplexing. A method of holographic data recording includes providing a holographic medium, providing a tunable blue-violet laser for wavelength multiplexing, and tuning the laser wavelength to record a hologram at a set wavelength and recording holographic data at the set wavelength on the holographic medium. A method for retrieving holographic data includes providing a holographic medium, providing at least one tunable blue-violet laser, tuning the blue-violet laser to a set wavelength, and retrieving holographic data at the set wavelength.
