Two-dimensional transition metal dichalcogenides (TMD), such as WS2 and MoS2, have been shown to exhibit large second order optical nonlinearity due to their non-centrosymmetric crystalline symmetry in few odd- and mono-layers, and resonance enhancement. Here we study the second-order nonlinear susceptibility of 2D TMDs through second harmonic generation (SHG) and sum frequency generation (SFG). Using a wavelength-tunable femtosecond laser, we can characterize SHG of TMDs to obtain the second-order nonlinear susceptibility at multiple wavelengths. Along with the experimental studies, theoretical investigation of the second-order nonlinear susceptibility is also performed. With this we explore the estimation of the second-order nonlinear susceptibility of 2D TMD layered materials based on their first-order susceptibility through the experimental and theoretical verification of Miller’s Rule for these materials. Additionally, we characterize the second-order nonlinear susceptibility of 2D TMD alloys through the SFG spectroscopy.
二维过渡金属二硫族化合物(TMD),如WS2和MoS2,由于其在奇数层和单层中的非中心对称晶体对称性和共振增强而表现出很大的二阶光学非线性。本文通过二次谐波产生(SHG)和和频产生(SFG)研究二维tmd的二阶非线性磁化率。利用波长可调的飞秒激光器,我们可以对tmd的SHG进行表征,从而获得其在多个波长下的二阶非线性磁化率。在实验研究的同时,对二阶非线性磁化率进行了理论研究。在此基础上,通过对二维TMD层状材料的米勒规则的实验和理论验证,探讨了基于一阶磁化率的二维TMD层状材料二阶非线性磁化率的估计。此外,我们还通过SFG光谱表征了二维TMD合金的二阶非线性磁化率。

Attosecond pulses generated in gases and solids (Conference Presentation) 气体和固体中产生的阿秒脉冲(会议报告)
Pub Date : 2018-08-31 DOI: 10.1117/12.2515253
P. Corkum
Attosecond pulses are generated by electrons that are extracted from a quantum system by an intense light pulse and travel through the continuum under the influence of the electric field of the light. Portions of each electron wave packet are forced to re-collide with its parent ion after the field reverses direction. Upon re-collision, the electron and ion can recombine, emitting soft x-ray radiation that can be in the form of attosecond pulses. This highly nonlinear process occurs in atoms, molecules and solids and offers unique measurement opportunities – for measuring the attosecond pulse itself; the orbital(s) from which it emerged; and the band structure of material in which the wave packets moved.
阿秒脉冲是由强光脉冲从量子系统中提取的电子产生的,这些电子在光的电场的影响下穿过连续体。在场方向逆转后,每个电子波包的一部分被迫与母离子重新碰撞。在再次碰撞时,电子和离子可以重新结合,释放出软x射线辐射,这种辐射可以以阿秒脉冲的形式出现。这种高度非线性的过程发生在原子、分子和固体中,为测量阿秒脉冲本身提供了独特的测量机会;由它产生的轨道;以及波包在其中移动的物质的带状结构。
