    Characterization of in-situ terahertz detection by optical interaction in a periodically poled stoichiometric lithium tantalate nonlinear crystal

    Terahertz waves are generated using a femtosecond laser pulse in a periodically poled stoichiometric lithium tantalate crystal and simultaneously detected via a non-collinear optical parametric interaction ins...

    Development of Laser Wavelength Conversion Devices for Selective Ablation of Dental Caries

    From the direct measurement of the onset energy density of the photoablation from 460 nm to 600 nm, it is found that wavelength between 520 nm to 560 nm has the best ablation selectivity. With the variations o...
