After revisiting models for the ferroelectric relaxors, we notice that the models can be classified into two categories. One group models are directly based upon the compositional fluctuations, such as Smolenskii's theory and SRBRF model. The other models are experimental phenomenon oriented, such as macro-micro domain crossover and superparaelectric state. The later explanations imply that the ferroelectric relaxor is in a critical state. The unusual field induced phase transition in ferroelectric relaxor also suggests that this is a critical phenomenon with first order phase transition feature. Therefore within the framework of effective field approach and with introducing the concept of quantum temperature scale, we reproduce the diffused phase transition of the dielectric constant and the field induced phase transition. It seems that the larger quantum fluctuation at low temperature depresses the ferroelectricity in ferroelectric relaxors, and results in their unusual physical properties.

钙钛矿结构的新型Tm∶GdScO_(3)晶体具有平坦且宽带(>450 nm)的增益光谱,可以产生2μm波段少周期激光脉冲。然而,目前该晶体的锁模激光特性,尤其是其各向异性的超短脉冲输出特性尚未明朗。采用b切的Tm∶GdScO_(3)晶体作为增益介质,通过共振泵浦被动锁模技术,详细研究了其E//a发光方向的飞秒脉冲输出特性,实现了60 fs激光脉冲产生(约9个光学周期),激光中心波长为2034 nm,光谱半峰全宽为80 nm,时间带宽积为0.35,接近傅里叶转换极限。该研究证明了Tm∶GdScO_(3)晶体是实现2μm波段少周期飞秒脉冲的理想激光材料,所获得的飞秒激光在分子超快动力学、高分辨率分子光谱学等科学研究领域极具应用潜力。
