    Extractions: The laser has become a major techno logical factor in today's fast paced world. CD-ROM, laser printers and even eye surgery all involve using a laser. In 1960, Theodore Maiman produced the first working laser [Bromberg, 1988]. The discovery marked the zenith of many years of research, and also the beginning of numerous technological breakthroughs. Because many parties in addition to Maiman contributed substantial research to the invention of the laser, a dispute arose over who should receive the patent for the invention of the laser. LASER is an acronym for "light amplification by stimulated emission of radiation." A laser produces a thin beam of light that is monochromatic and coherent, meaning that the beam is one color and each wave of lighttravels in step. The laser process begins when energy enters and begins to strike the atoms in a system. The stimulated atoms give off energy in the form of light. This emitted light reflects back and forth between the ends of a cylinder, one end being a fully reflecting mirror and one end being a partially reflecting mirror. The light continues to excite more and more atoms, and finally the atoms contain enough energy to burst through the partially reflecting mirror in a beam of light. This beam of light has a variety of applications. For instance, it is able, in some cases, to drill tiny holes in diamonds within minutes (conventional methods take days to produce the same holes).

He also serves on the Board of Trustees of Southeastern Seminary. Professor Charles Townes is one of the most brilliant scholars of the 20th Century and has earned a distinguished reputation for being hard working, honest, and forthright. Professor Townes is a committed Christian and a deep thinker who will share with us his thoughts on ways in which scientific and religious thinking are converging at the threshold of the 21st Century. His presentation will begin at 7 pm on Thursday, October 14, 1999 in Rudder 601.

    Extractions: A Brief History of Lasers: The principle of the laser was first known in 1917, when physicist Albert Einstein described the theory of stimulated emission. However, it was not until the late 1940s that engineers began to utilize this principle for practical purposes. At the onset of the 1950's several different engineers were working towards the harnessing of energy using the principal of stimulated emission. At the University of Columbia was Charles Townes, at the University of Maryland was Joseph Weber and at the Lebedev Laboratories in Moscow were Alexander Prokhorov and Nikolai G Basov. At this stage the engineers were working towards the creation of what was termed a MASER (Microwave Amplification by the Stimulated Emission of Radiation), a device that amplified microwaves as opposed to light and soon found use in microwave communication systems. Townes and the other engineers believed it to be possible create an optical maser, a device for creating powerful beams of light using higher frequency energy to stimulate what was to become termed the lasing medium. Despite the pioneering work of Townes and Prokhorov it was left to Theodore Maiman in 1960 it invent the first Laser using a lasing medium of ruby that was stimulated using high energy flashes of intense light (see example) Both Townes and Prokhorov were later awarded the Nobel Science Prize in 1964 for their endeavours.

Contact Us Printer Friendly Version June 12, 2003 The SETI Institute is pleased to announce the appointment of Dr. Charles H. Townes to the Institute’s Board of Trustees , effective June 5. Winner of the 1964 Nobel Prize in Physics for his invention of the laser, Townes' addition will expand the exceptional scientific expertise that distinguishes the SETI Institute Board. Says SETI Institute CEO, Thomas Pierson, “Charles Townes is well known for his technological innovations, his ability to see the potential of new scientific ideas, and his effective leadership in the numerous advisory roles in which he has served. We couldn’t hope for a better fit for our governance body.” Townes is currently Professor Emeritus and professor in the graduate school of physics at the University of California, Berkeley. While much of his recent research has been directed towards understanding the galactic center and other objects in the Milky Way, Townes has retained a long-standing interest in SETI, and his pioneering theoretical work in the field led to the development of today’s optical SETI projects. In 1997, Professor Townes participated in a SETI Institute

    Extractions: Images The prize consists of a cash stipend and a special award, and will be presented at a ceremony in the spring of 2003. Townes is the second recipient of the Drake Award, which was launched in 2001 with a presentation ceremony honoring its namesake, Dr. Frank Drake. Townes is the first honoree selected from a pool of candidates whose submissions were solicited by the Institute. The recipient of numerous awards and 25 honorary doctorate degrees throughout his career, Townes' principal scientific work is in microwave spectroscopy, nuclear and molecular structure, quantum electronics, radio astronomy and infrared astronomy. He holds both the original patent for the maser, and (with Arthur Schawlow) the original laser patent. In 1964, he received the Nobel Prize in Physics for his work in quantum electronics, which led to the construction of maser and laser oscillators and amplifiers. Acknowledging that radio technology matured more quickly than optical, Townes consistently maintained that other technologically advanced civilizations could exploit the optical and infrared spectrum for communications just as readily as the microwave spectrum. In two later papers, one published in 1982 and another in 1993, Townes compared the relative strengths and liabilities of optical and radio SETI, concluding that both research methods should be conducted.

He was a pioneer in microwave and infrared astronomy and led the team at Berkeley which, in 1968, discovered water and ammonia molecules in interstellar space. Townes has a long-standing interest in the possibly of optical SETI and while at the Massachusetts Institute of Technology in the early 1960s was the first, together with R. N. Schwarz, to suggest the possibility of using lasers for interstellar communication. He is presently involved in a project, funded by the Planetary Society , to search for artificial laser pulses coming from a variety of sources, including nearby stars, globular clusters , and external galaxies.
