摘要

我们介绍了在脉冲激光辐射的控制作用下，由相变材料 Ge2Sb2Te5 制成的基本可控池中形成的层状结构所引起的光束相移的自由空间光学控制实验研究。演示了在杰明干涉仪中，通过相变材料可控池的信号光束相对于控制光束的相位变化。

Optically Controlled Fine-Tuning Phase Shift Cell Based on Thin-Film Ge2Sb2Te5 for Light Beam Phase Modulation

We present the experimental study of free-space optical control of the optical beam phase shift caused by the formation of a layered structure in an elementary controllable cell made of phase-change material Ge₂Sb₂Te₅ subjected to the controlling effect of pulsed laser radiation. The phase change of the signal optical beam passing through the controlled cell from phase-change material relative to the control beam in the Jamin interferometer is demonstrated.
