摘要：
Optical information has been stored on the metal film by femtosecond laser pulses with the aid of the computer-generated hologram (CGH). The Fourier transform of an object is performed by a computer, and then the resulted complex amplitude distribution is encoded by the detour phase method. The resulted cell-oriented CGH is directly written on the metal film deposited on the glass substrate using femtosecond laser by selective ablation. The object wave has also been reconstructed with high fidelity by using a collimated He-Ne laser beam.
