The processes of creation of luminescence centers by laser radiation in transparent anisotropic crystals are investigated using MgF₂ as an example. To monitor the concentration of the created centers, a luminescent method was developed, which ensured a direct proportionality between the luminescence intensity and the concentration of centers. By the joint action of coherent pairs of femtosecond laser pulses, the longitudinal positioning of the action of light on the medium was performed during the creation of spatially modulated structures. Laser filaments resulting from self-focusing contained both ordinary and extraordinary components. A simple method is substantiated for studying the efficiency of the formation of quantum systems depending on the polarization state of the acting radiation in one experiment. It is shown that the experiments implemented an intermediate mechanism of multiphoton-tunneling ionization of a crystal during laser defects formation.

使用MgF ₂研究了透明各向异性晶体中激光辐射产生发光中心的过程。举个例子。为了监视创建的中心的浓度，开发了一种发光方法，该方法确保了发光强度与中心的浓度之间成正比。通过飞秒激光脉冲的相干对的共同作用，在空间调制结构的创建过程中，将光作用在介质上进行了纵向定位。自聚焦产生的激光灯丝同时包含普通成分和非常规成分。在一个实验中，证实了一种简单的方法来研究量子系统形成的效率，该效率取决于作用辐射的偏振态。结果表明，实验实现了激光缺陷形成过程中晶体的多光子隧道电离的中间机制。
