Abstract

An effect of nonstationary amplification of the holographic recording in pure and transition-metal doped crystals of the sillenite type (Bi(12)SiO(20), or BSO), irradiated in advance with light from the red or near-infrared spectrum, is investigated. This amplification can serve as a base for incoherent-tocoherent optical conversion. It is found that BSO crystals doped with iron and cobalt have a highersensitivity and much wider spatial-frequency range, where the effect of the amplification can be observed,compared with nondoped crystals.

摘要

研究了在预先用红色或近红外光谱的光照射的纯的和过渡金属掺杂的亚硒酸盐型晶体（Bi(12)SiO(20)，即BSO）中全息记录的非平稳放大效应。这种放大可以作为非相干到相干光学转换的基础。发现与未掺杂的晶体相比，掺杂铁和钴的BSO晶体具有更高的灵敏度和更宽的空间频率范围，在该范围内可以观察到放大效应。
