摘要

针对氟化锂晶体，找到了测量飞秒激光脉冲作用下形成的纤丝发光强度的正确条件。所确定的条件确保了测量强度与激光辐射在晶体中形成的发光颜色中心的浓度成正比，从而可以得出关于灯丝中发生的过程的结论。我们发现了近似色团的颜色中心，这表明在灯丝的所有区域都存在纳米级的色团。

Luminescence Characteristics of Filaments in Lithium Fluoride Crystals

The correct conditions for measuring the luminescence intensities in fi laments formed by the action of femtosecond laser pulses were found for lithium fluoride crystals. The determined conditions ensured that the measured intensities were proportional to the concentrations of luminescent color centers created in the crystals by the laser radiation and allowed conclusions to be drawn about the processes occurring in the filaments. Near-cluster color centers were found, indicating the presence of nanosized clusters in all areas of the fi laments.
