  • METHOD AND APPARATUS FOR LIPID REMOVAL USING INFRARED OPO LASER
    Publication number: 20130066300
    Abstract: The present invention relates to a method and an apparatus for lipid removal using infrared OPO laser. Specifically, the method and the apparatus can remove fat from a living body in a more energy-efficient, rapid and effective manner by irradiating fat in the living body directly with two infrared lasers having wavelengths of about 2,300 nm and about 1,980 nm, which are generated using a pump laser having a wavelength of about 1,064 nm as a light source.

  • ZEOLITES WITH INCORPORATED DIPOLAR NONLINEAR OPTICAL MOLECULES IN UNIFORM ORIENTATION AND PREPARATION THEREOF
    Publication number: 20060219989
    Abstract: The present invention relates to a method for preparing a uniformly aligned zeolite supercrystal, which comprises growing a crystal of a zeolite or zeotype material in a uniformly aligned template, whereby said uniformly aligned zeolite supercrystal is prepared, and a uniformly aligned zeolite supercrystal. The uniformly aligned zeolite supercrystal of this invention would be anticipated to maximize its applicability by overcoming the shortcomings of zeolites with random orientation.

  • High-density optical disk with a polymer film featuring thermochromism
    Patent number: 6808779
    Abstract: The present invention relates to a high-density optical disk having thin film layer made from a thermochromic polymer with a red-shift which exhibits self-focusing and optical bleaching. After an incident light beam passes through the polymer medium, not only can the spot size of the beam be reduced but also transmittance can be enhanced due to these kinds of third-order nonlinear optical response. Thus, a high-density disk structured according to the present invention is capable of the signal reproduction resolution beyond the diffraction limit with an efficient reflectivity. Accordingly, data recording density of a high-density disk can be improved greatly.
