光子选通光化学烧孔(Photon-gated photochemical hole burning)作为一种信息记录方法——频域光学存储,其记录密度可高达10~9—10~11位/cm,又由于其具有阈值条件,克服了单光子光化学烧孔法记录信息在多次读取后失真的缺点,引起了人们极大的兴趣。
Photon-gated photochemical hole burning as a method of information recording - frequency domain optical storage, the recording density of up to 10 ~ 9-10 ~ 11 / cm, and because of its threshold conditions, Overcomes the shortcoming that single-photon photochemical burn-in method records information after being read many times, causing great interest.
