	Ali Javan
		Javan is still intensely involved with inventions, concentrating on the use of matter at "nano-scale", specifically working on electronics at optical frequencies.
		Ali Javan is the Francis Wright Davis Professor of Physics at the Massachusetts Institute of Technology.
		Dr. Ali Javan was too busy to meet but being the gentleman that he is, he spent nearly an hour on the phone trying to convince me that he didn't have time for an interview.

		Born in 1928 in Tehran of Azeri parentage, Ali Javan came to the United States in 1949 where he received his Ph.D. in Physics at Columbia University in New York City in 1954.
		Shortly after the invention of the Helium-Neon Laser, Javan conducted the first experiment of a telephone conversation ever to be transmitted by laser beam.
		Following Javan's invention, laser research at industrial labs and universities has grown in various directions, as has the laser industry itself.

		Having made pioneering contributions to applied laser technology, Ali Javan’s most significant invention is the helium-neon laser, the most useful, practical, and profitable type of laser in use today.
		Born in Tehran, Iran, Javan came to the U.S. in 1948 and earned his Ph.D. in physics from Columbia University in 1954.
		Javan continued his research at Bell Labs, where he conceived the gas laser principle, which led him to invent a laser composed of helium and neon.

		Ali Javan was the first person to invent the gas laser.
		The light, which is reflected back and forth between the two mirrors, increases exponentially at the speed of light and builds up in intensity, resulting in the laser light output from the laser apparatus.
		Javan succeeded in building the first continuous laser light beam on December 12, 1960 at 4:20pm.

		Creating the population inversion necessary to generate laser action required so-called optical pumps, such as flash lamps, and these could only produce a pulse of energy rather than continuous laser light and were not efficient in the use of power.
		Another quite different version, developed later in 1960 by Ali Javan at Bell Laboratories, used a glass tube containing a mixture of the gases helium and neon.
		This laser had a lower energy threshold and did not overheat, but the glass tube was both bulky and fragile.

		In 1958, Townes and Arthur Schawlow calculated the conditions needed to produce visible laser light, but it was not until 1960 that the first laser was finally presented, when Ted Maiman developed the ruby laser.
		The first gas laser created was a helium neon laser, created by Ali Javan.
		It was first demonstrated on December 12, 1960 at Bell Telephone Laboratories in New Jersey.

	IR Maser Offers First CW Coherent-Light Source (Site not responding. Last check: 2007-10-03)
		The gas-discharge principle used in this first cw source of coherent light could prove applicable in a wide variety of gases and gas mixtures, according to Bell scientist Dr. Ali Javan, inventor of the device.
		Javan also indicated that later versions of gas discharge masers might operate at wavelengths as short as 5,000 Å.
		Such a "green" maser would be of considerable interest to Navy scientists who believe that a transmission "window" in sea water at about 5,000 Å may permit submarine detection by a form of light radar.

		I think the teachers must have recognized something in me. They provided me with a tremendous background in math and physics and pushed me to explore concepts far beyond what was offered in the curriculum.
		When I came to the United States in 1949 after finishing high school, I started taking heavy graduate courses in physics and math at Columbia University (New York).

		Continuous lasers can deliver hundreds of watts of power, and pulsed lasers can produce millions of watts of power for very short periods.
		Developed during the 1950s and 1960s, largely by the American engineer and inventor Gordon Gould and the American physicists Charles Hard Townes, T. Maiman, Arthur Leonard Schawlow, and Ali Javan, the laser today has become an extremely powerful tool in research and technology, with applications in communications, medicine, navigation, metallurgy, fusion, and material cutting.
		The construction of large and specially designed optical telescopes has led to the discovery of new stellar objects, including a number of quasars, which are billions of light-years away, and has led to a better understanding of the structure of the universe.

	Azeris in Iran - Wikipedia, the free encyclopedia
		Azeris in Iran are in high positions of authority with the Ayatollah Ali Khamenei currently sitting as the Supreme Leader.
		In addition, the current Supreme Leader of Iran, Ali Khamenei, is an Azari, along with much of Iran's military and political leadership, a fact which seriously undermines claims of discrimination of Azaris in Iran or that they do not have equal opportunities compared to other ethnic groups in Iran, such as Persians.
		However, At the end of June 2005, scores of people were reportedly arrested following an Azari gathering at Babak Castle in the city of Kalaybar.

	The Flynn Group -- About Professor Flynn (Site not responding. Last check: 2007-10-03)
		As a graduate student at Harvard University from 1960-1964, George Flynn studied nuclear relaxation processes in simple fluorocarbons under the direction of Professor John D. Baldeschwieler, and also investigated rotational relaxation of gases using microwave double resonance techniques under the direction of Professor E. Bright Wilson, Jr.
		He received his Ph.D., from Harvard Unversity in 1965 and for two years (1965-1966) he did postdoctoral work in the Optical Maser (Laser) research group in the Physics Department of the Massachusetts Institute of Technology under the direction of Professor Ali Javan.
		His work at M.I.T. consisted of the development of Q-switching techniques in molecular gas lasers and the use of these techniques to study molecular vibrational relaxation processes.

		The atoms in the higher energy states could be stimulated to emit radiation by a very weak light signal of the proper frequency, which would create a cascade that would stimulate the emission of light by all other atoms in the higher energy state, producing a strong pulse of red light.
		About the same time, Ali Javan and his collaborators at Bell Laboratories discovered a way to create a population inversion in a mixture of helium, neon, and other gases.
		The tube in which these gases were placed was irradiated continuously with light of the appropriate wavelength.

		This produced continuous radiation at low power but with a very pure frequency and the narrowest possible beam.
