After receiving a pumping flash from the flash tube, the laser light emerges for as long as the excited atoms persist in the ruby rod, which is typically about a millisecond. Construction. First demonstration of laser action using ruby crystal was given by T.H. May 16, 1960: Theodore H. Maiman, a physicist at Hughes Research Laboratories in Malibu, Calif., constructs the first laser using a cylinder of synthetic ruby measuring 1 cm in diameter and 2 cm long, with the ends silver-coated to make them reflective and able to serve as a Fabry-Perot resonator. Laser - Laser - History: The laser is an outgrowth of a suggestion made by Albert Einstein in 1916 that under the proper circumstances atoms could release excess energy as light—either spontaneously or when stimulated by light. The laser medium can be a solid, gas, liquid or semiconductor. One end of rod is fully silvered and the other one partially silvered so it act as optical resonator. For further cooling the jacket of liquied nitrogen is used at the outermost surface of the ruby maser. Advantages of the ruby laser. Ruby laser construction and working.
