光限制效应在激光防护及军事等方面有着重大的应用前景。有关其机理及材料的研究一直是近年来光学研究的重要领域之一。反饱和吸收过程作为光限制的重要机理已被普遍认为是最可能使先限制获得的实际应用之一。有机分子（如酸氢分子和C6。）是典型的反饱和吸收介质，已显示出很 Optical confinement effect in laser protection and military has a significant application prospects. Research on its mechanism and materials has been one of the important fields of optical research in recent years. The anti-saturation absorption process as an important mechanism of light limitation has generally been considered as one of the practical applications that is most likely to lead to the first restriction. Organic molecules (such as acid-hydrogen molecules and C6.) Are typical reverse-saturating absorption media and have shown to be very
