Multiwatt CW Diode End-Pumped Nd:YAP All-Solid-State Laser

在本论文中,我们首先分析了Nd:YAP晶体的物理、化学性质和能级结构，测量并标定了a轴切割Nd:YAP激光晶体在400nm-950nm的偏振吸收谱，并对我们感兴趣的780nm-825nm波段进行了详细的标定与讨论。同时，我们提出一种简单的偏振光谱分析法，并在首次考虑各向异性激光晶体的色散关系情况下，测量并标定了a轴切割Nd:YAP激光晶体在三个主要跃迁波段4F3/24I9/2，4F3/24I11/2和4F3/24I13/2的偏振受激发射截面光谱，并对所得数据进行了必要的讨论以优化激光腔体参数设计。 其次，本文在前人的基础上建立了四能级系统激光运...In my master thesis, Fluorescence spectra of Nd:YAP were experimentally measured. A spectroscopic determination method was employed to calculate the polarized stimulated emission cross section spectra of the three principal transitions (4F3/24I9/2，4F3/24I11/2 and 4F3/24I13/2) for a-cut Nd:YAP laser crystals，where the dispersion relation of Nd:YAP crystal is also considered ...学位：理学硕士院系专业：物理与机电工程学院物理学系_光学学号：20002402

Nd∶YAP的偏振光谱性质的研究

提出一种简单的偏振光谱分析法,并考虑在各向异性激光晶体的色散关系情况下,测量并标定了a轴切割Nd∶YAP激光晶体在3个主要跃迁波段4F3/2→4I9/2,4F3/2→4I11/2和4F3/2→4I13/2的偏振受激发射截面光谱.该偏振光谱法简单易行,且精度高,所标定的结果可为激光器件的设计和理论分析提供重要的光谱数据

Nursing of two patients with suspected Creutzfeldt-Jakob disease (2例疑似克雅氏病患者的护理)

To summarize the nursing experiences of two patients with suspected Creutzfeldt-Jakob disease (CJD). Because of the complex clinical manifestation and rapid course of CD, nurses caring for patients and families are challenged to understand the nature of CJD, manage the patients’ signs and symptoms, and create a therapeutic experience by integrating the psychological, emotional, spiritual, and social components of nursing care. During the hospitalization, nurses had closely observed the changes of patients’ conditions, maintained the patients’ airway unobstructed, strictly executed the disinfection and isolation rules, and carried out the corresponding protection and nursing. Neither patient had any nursing related complications or cross infection during hospitalization. (本文总结2例疑似克雅氏病患者护理的经验。克雅氏病临床表现复杂, 病程进展快速, 临床护士需要了解克雅氏病的本质, 管理患者的症状和体征, 并通过整合护理的心理、情感、精神和社会组成部分来创造治疗经验。在院期间, 应严密观察病情变化, 保持患者呼吸道通畅; 严格执行消毒隔离制度, 做好相应消毒隔离的防护护理。2例患者住院期间未发生护理相关并发症, 未出现交叉感染。
