研究目的
To investigate the control of photoluminescence properties of Nd:YAG crystals by laser irradiation, focusing on the effects of different laser parameters on the crystal defects and their photoluminescence emission.
研究成果
Laser irradiation can control the photoluminescence properties of Nd:YAG crystals by either suppressing or generating defects, depending on the irradiation parameters. This has significant implications for solid-state laser and scintillator applications.
研究不足
The study is limited to the effects of ArF and XeCl laser irradiation on Nd:YAG crystals. The interpretation of photoluminescence spectra requires detailed knowledge of the energy levels caused by defects and impurities.
1：Experimental Design and Method Selection:
The study involved irradiating Nd:YAG crystal samples with ArF and XeCl lasers under different conditions to observe changes in photoluminescence properties.
2：Sample Selection and Data Sources:
Nd:YAG single crystal samples with 1 at.%Nd3+ were used, polished to specific dimensions.
3：List of Experimental Equipment and Materials:
ArF laser (Lambda Physik X200), XeCl laser (Lambda Physik X100), and a photoluminescence spectroscopy system (Gliden Photonics, UK) were employed.
4：Experimental Procedures and Operational Workflow:
Samples were irradiated perpendicular to the laser beam under various conditions, followed by photoluminescence measurements.
5：Data Analysis Methods:
Photoluminescence spectra were analyzed to identify changes in emission peaks related to crystal defects.
