Crystals KTiOPO4 and KTiOAsO4 are used in terahertz parametric oscillators. The transverse optical A1 mode associated with the stimulated polariton scattering for KTiOPO4 is 268.5 cm−1. The intermittently tunable THz wave from 3.17 THz to 6.13 THz is obtained. For KTiOAsO4, the transverse optical A1 mode is 233.8 cm−1 and the intermittently tunable range is from 3.59 THz to 6.43 THz. The appearance...
Stimulated Raman scattering (SRS) is one of most efficient methods for generating new laser lines. In recent years, SRS in crystalline Raman media have attracted much attention for the advantages of high Raman scattering gain, favorable thermal conductivity and good mechanical and chemical stability [1-3]. So far most crystalline Raman lasers focus on Stokes generation. In contrast to Stokes generation,...
Researchers have not specifically considered the determinants of post-purchase intention with regard to online insurance purchases. By consulting DeLone and McLean's ISS model, this study develops and empirically examines a model of the impact of system quality, information quality, and perceived product complexity on post-purchase intention in this context. Data collected from 177 online-insurance...
Replication of human body motion is a very important means to maintain a subject's emotion, knowledge and experience. The replication process requires accurate motion capturing system with sensor technologies to measure postures of human bodies and posture transmission, as well as feedback systems to adjust postures to fit into targeted ones. The sensing and feedback technologies are fundamental building...
