To adequately model information exchanged in real human-human interactions, considering speech or text alone leaves out many critical modalities. The channels contributing to the “making of sense” in human-human interactions include but are not l

We demonstrate a novel method for efficient frequency tripling of 1064-nm infrared beam. The walk-off in the frequency mixing is doubly compensated for, resulting in an improvement of the conversion efficiency and ultraviolet beam profile.

We report a high repetition rate Q-switched Nd:YVO4/Cr4+:YAG micro laser with small pump power. Unwanted defects in pulse train, which are inherently large in passively Q-switched laser, was simply minimized by controlling temperature of Nd:YVO4/Cr4+

A method for transforming planar electronic devices into 3D structures under mechanically mild and stable conditions is demonstrated. This strategy involves diffusion control of acetone as a plasticizer into a spatially designed acrylonitrile butadie

Coherent tunable terahertz generation was demonstrated in periodically poled stoichiometric lithium tantalate crystal via difference frequency generation of femtosecond laser pulses. Simultaneous forward and backward terahertz radiations were obtaine

A high-conversion efficiency, nanosecond pulsed optical parametric generation and amplification with repetition rate of 20 kHz based on a periodically poled MgO-doped stoichiometric lithium tantalate was presented. Pumped by a Q-switched $Nd:YVO_4$ l

We have investigated the terahertz radiation generated by femtosecond laser pulses in a periodically poled lithium niobate crystal. Two different types of terahertz radiation, forward and backward, could be generated in quasi-phase-matching structure

We propose a novel walk-off-compensation method for ultraviolet-light-source development. A walk-off occurring in the frequency mixing of infrared and green beams is doubly compensated for using an external walk-off compensator and a nonlinear-materi
