Hughes Research Laboratories

The first known laser was made by Theodore Maiman at Hughes Research Laboratories in Malibu, California, in 1960, but the seeds of this breakthrough were planted years before. In 1917 Albert Einstein, through his work on the quantum theory of light, theorized that stimulated emission of light radiation could occur. The idea was forgotten, though, until the middle of the century.

The D Mw values for a series of CMS-MOTSS copolymer compositions are shown in Figure 3 with the lines calculated from the above formula using two D Mw values for the PCMS homopolymer.. Extrapolation of the experimental data suggests that the actual D Mw value for the PCMS homopolymer is 0.057, midway between our earlier value of 0.046 (Jensen, J.E. Brault, R.G. Miller, L.J. Granger, D.D. van Ast, C.I., Hughes Research Laboratories, unpublished results) and that of 0.07 used by Tanigaki et al. (11)-... 

There are many solid state lasers. One of the most commonly treated types in laser textbooks is the ruby laser (Al203 Cr +), which was the first laser system demonstrated by T. H. Maiman at the Hughes Research Laboratory early in 1960 (Maiman, 1960). Figure 6.9 in Chapter 6 will show the quantum energy levels associated with the unfilled 3d inner shell of the Cr + ion when it substitutes for the AP+ ion in the AI2O3 lattice crystal. By using a ruby rod placed inside a spiral flashlamp filled with a hundreds of torrs of xenon, it is possible to optically pump Cr + ions from the " A2g ground state into the broad " T2 and " Ti bands of the excited levels. After a rapid relaxation down to the very sharp Eg level, laser emission can be produced at 694 nm via the Eg " A2g transition.

The term laser is an acronym for light amplification by stimulated emission of radiation. A typical laser emits light in a narrow, low-divergence beam, with a narrow wavelength spectrum ( monochromatic light) [1-6]. The first working laser was demonstrated by Theodore Maiman on May 16, 1960 at Hughes Research Laboratories. 

In 1960, Theodore Maiman of the Hughes Research Laboratories produced the first laser using a ruby crystal as the amplifier and a flash lamp as the energy source. The helical flash lamp surrounded a rod-shaped ruby crystal, and the optical cavity was formed by coating the flattened ends of the ruby rod with a highly reflecting material. In operation, an intense red beam emerged from the ends of the rod when the flash lamp was initiated. 

In 1960, American physicist Theodore Maiman of Hughes Research Laboratories developed the pulsed ruby laser. This laser used rubies to operate and generated powerful bursts of light lasting only nanoseconds. This laser, which acted much like a camera s...

All students are required to participate in a summer research internship off campus for at least one summer during their career. However, many students participate in more than one. Students work with people like Tom Cech, a Nobel laureate and the president of Howard Hughes Medical Institute. He has taken at least two Meyerhoff students in his lab for the past six years. There are international internships as well, in places such as England, France, and Rio de Janeiro. These students work in top research laboratories where they participate actively in a research project, many times resulting in publications.
