论述了光谱烧孔技术的动力学理论模型 ;介绍了单光子烧孔和多光子烧孔所取得的实验结果 ;讨论了光谱烧孔的发展趋势 :提高烧孔度 ,实现室温烧孔和提高探测及读出时的信噪比。问题的关键在于光致填孔机制的研究。同时提出将它投入实际应用亟待解决的问题 ,即作为一种可能的高密度频域光信息存储手段所亟待解决的问题是开发适应于此技术的新材料 ,深入研究材料体系的烧扎特性 The kinetic theory model of spectral hole burning technology is discussed. The experimental results obtained by single photon burning hole and multiphoton burning hole are introduced. The developing trend of spectral burning hole is discussed: the burning hole degree is increased, And read the signal to noise ratio. The crux of the problem lies in the research of photofilling mechanism. At the same time put forward to put it into practical application of the problem to be solved, that is, as a possible high-density optical information storage means the urgent need to solve the problem is to develop new materials adapted to this technology, in-depth study of the material properties of the burning characteristics
