High-technology laser systems: gas laser holography methods in medicine

Holography methods require high-technology laser systems and, just like interpherometery, are often used in ophthalmology. Certain researches have high potential in this sphere: three-dimension image of the eye and its parts, studying optical eye features and measuring internal eye structures with the high resolution. Most of the research today is about creating an image of...

Atomic Cooling: scientific laser systems (laboratory laser, laser equipment)

Since 1976 scientists have been working on the idea of controlling (cooling, trapping) atoms with laser equipment. The atom trapped in the laboratory laser beam absorbs photons and becomes excited; photons can transmit their impulses to the atom. When atoms are de-excited, they reemit photons in random directions. As a result the atom experiences light...
