Abstract: A tracking system utilizing an excited state atomic line filter. The filter includes a metal vapor cell having an optical entrance port and an optical exit port and containing a metal vapor having a first excited energy state with a resonant frequency, and a second excited energy state. The cell has an absorption line, at or near a desired filter wavelength. The platform to be tracked, which could be an un-manned aerial vehicle has a beacon laser system located on it for producing a beacon laser beam at a wavelength within the narrow spectral band. The present invention solves the problem of lack of ground state resonant lines in at wavelengths substantially longer than those of visible light. Atomic line filters of the Faraday or Voigt crossed polarizer type are provided in which alkali metal atomic vapor in a vapor cell is excited with a pump beam to an intermediate excited state where a resonant absorption line, at a desired wavelength, is available. A magnetic field is applied to the cell producing a polarization rotation for polarized light at wavelengths near the resonant absorption lines. Thus, all light is blocked by the cross polarizers except light near one of the spaced apart resonant lines. However, the polarization of light at certain wavelengths near the resonant is rotated in the cell and therefore passes through the output polarizer.

Additional hair removal methods include infiltrating a photoactivated drug into hair ducts and exposing the skin to sunlight or administering an anti-proliferative agent into hair ducts, for example, by encapsulating the anti-proliferative agent in a slow release vehicle. The methods of treating Herpes virus, reducing sweat or body odor, and removing keloid or hypertrophic scars include infiltrating a light-absorbing contaminant into hair ducts or other openings in the skin and illuminating the contaminated skin section. The methods for stimulating hair growth include grafting of cloned auto hair stem cells the hair ducts or administering methionine to a skin section to increase hair growth. Apparatus useful in performing these methods include devices for making a smooth optical boundary between skin and air or for dividing a light beam into a plurality of smaller light beams, and dressings for use before, during and after laser illumination.

Abstract: Methods of applying laser light to the skin, and apparatus therefor, include methods for removing hair, for bleaching hair, for transdermal drug delivery, for sensing a body function, for skin tightening, and for imaging subsurface structures are described. The hair removal methods and the hair bleaching methods include infiltrating a transparent fluid with an index of refraction greater than that of skin tissue into hair ducts to help transmit the laser light down the hair ducts. The transdermal drug delivery and body function sensing methods include exfoliating layers of the stratum corneum from a section of skin with laser light. A transdermal drug delivery patch can be placed over the exfoliated skin section, or an electrical sensor can be placed over the exfoliated skin section. The skin tightening method includes implanting a light absorbing material in the dermis of a section of skin and illuminating the skin section to disturb the dermis in such a way as to cause a healing reaction that forms more collagen fibers. The imaging system includes a confocal microscope that has been adapted to view only a time-gated portion of laser light reflected from the skin.

Abstract: A process for the long term or permanent prevention of growth of unwanted hair. The upper portions of hair ducts (i.e. portions near the skin surface) in a section of skin are infiltrated with a contaminant having a high absorption at at least one frequency band of light. The skin is then illuminated using a process having at least two distinct phases. In a "mechanical" phase the skin section is illuminated (e.g., by a laser) with at least one short pulse of light sufficient to cause tiny explosions in the contaminant forcing portions of the contaminant more deeply into the hair ducts. During a "thermal" phase the skin section is then illuminated so as to heat the contaminant substantially without further explosion or vaporization of the contaminant. The hot contaminant heats portions of the skin tissue immediately surrounding the contaminant to a temperature high enough and for a long enough period of time to devitalize the tissue. The process may also include a "cleanup" phase, during which the skin section is illuminated with a few short pulses of light to cause additional explosions in and vaporization of portions of the contaminant then remaining in the ducts and additional damage to the skin tissue immediately surrounding the contaminant.
