    Abstract: In this patent, we teach methods to generate coherent X-ray and UUV rays beams for X ray and UUV microscopes using intense femtosecond pulses resulting the Ultra-Supercontinuum (USC) and Higher Harmonic Generation (HHG) from χ3 and χ5 media produce from electronic and molecular Kerr effect. The response of n2 (χ3) and n4 (χ5) at the optical frequency from instantaneously response of carrier phase of envelope results in odd HHG and spectral broadening about each harmonic on the anti-Stokes side of the pump pulse at wo typically in the visible, NIR, and MIR. From the slower molecular Kerr response on femtosecond to picosecond from orientation and molecular motion on n2 and n4 which follow the envelope of optical field of the laser gives rise to extreme broadening without HHG. The resulting spectra extend on the Stokes side towards the IR, RF to DC covering most of the electromagnetic spectrum. These HHG and Super broadening covering UUV to X rays and possibly to gamma ray regime for microscopes.

    Abstract: There is a need for a compact instrument and microscope that maps the vibration fingerprints of biomolecules and chemicals in a sample such as brain, breast, cervix, and arteries. One can use spontaneous Raman scattering to accomplish this; however, the problem is low scattering efficiency to 10−5. With the availability of continuous wave diode laser at numerous wavelengths from 375 nm-1800 nm for parametric nonlinear difference vibrational mixing to enhance Stimulated Raman process within materials. A seed beam at Raman frequency is used with pump laser beam. In this way one can map in 2D and 3D images of the vibrations associate with disease changes. Scanning a pair of laser beams can map the location of vibrations within cells, smears, membranes, arteries, and tissues of animal and human.

    Abstract: Spatial frequency spectra from periodic, aperiodic and quasi-random structures in materials are shown and used to detect differences among objects via internal coding from the spatial frequencies. The method is applied to different grades of human tissues for a new form of histology and pathology, and to detect art forgeries and coding boxes, money and papers and gems. The randomness of material structures on surface and at depths near surface can be detected from the spatial spectrum. In tissue spectral features from normal to different stages of cancer in tissue for ex vivo and in vivo applications can be recognized by different spectral fingerprints content of the spatial frequency. Similarly, the painting for the strokes of artist is different. A new type of instrument is described to analyze materials as a Spatial Frequency Spectrometer.

    Abstract: A compact random media size antenna employing random magnetic and dielectrics nm to mm range size particles in polymer hosts is used to transfer E & M oscillations in 1 kHz to 900 Mhz range using a 1 cm to 1 meter length antenna. This is achieved by using small size particles and a random mean path length of E & M wavefront travel in and about a core tube of effective length matching Leff=L2/2ltr, equivalent to λ/2 for transmitting and receiving E & M radiation, where L is the physical size of the antenna, ltris the transport scattering random walk length between particles and λ is the frequency wavelength.

    Abstract: A rectal near infrared (NIR) scanning polarization imaging system uses NIR Photonic Prostatoscopy Analyzer (NIRPPA) for prostate cancer detection using light. The NIRPPA consists of a portable rectal NIR scanning polarization imaging unit and an optical fiber-based rectal probe capable of recording sets of 2D images of a prostate through rectum at different wavelengths and depths and obtaining a three dimensional (3D) image of the prostate and 3D locations of abnormal tissue inside the prostate. Diode lasers/light emission diodes (LEDs) with selected emitting wavelengths are used in the NIR spectral range from 650 nm to 2,400 nm corresponding to the four tissue optical windows (#I, 650 nm-950 nm; #II, 1,100 nm-1,350 nm; #III, 1,600 nm-1,870 nm; and #IV, 2,100 nm-2,300 nm). The fingerprint absorptions of water (H2O), Oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) in the prostate are used as native biomarkers for prostate cancer detection.

    Abstract: A method for welding tissue wounds in an animal. The method comprises joining edges of a tissue wound and irradiating the tissue wound and tissue surrounding the tissue wound with a pulsed laser. The pulsed laser has a laser wavelength in a range of an absorption band of water, elastin and/or collagen in the tissue wound and tissue surrounding the tissue wound. The pulsed laser has a pulse width of not more than picoseconds in order of magnitude to heat tissue surrounding the tissue wound and facilitate bonding of native tissue protein present in the tissue surrounding the tissue wound to achieve tissue repair. The laser wavelength is in a range of between about 800 nm to about 2,700 nm.
