Advanced Laser Source Research

Abstract

We now have a laser system which allows us to observe electromagnetically induced transparency in regions never before accessible. Briefly, the system produces two wavelengths (i.e., 406 nm and 283 nm), each with a frequency stability of several MHz and with energy of several mJ. Using this system, we are now able to observe an increase in transparency of over a factor of 10,000 in an exponent. We also observe optical group velocities as slow as c/100. We are beginning the observation and study of large signal effects. The other important area of work this year has been the identification of the normal modes of electromagnetically induced transparency. These modes follow from the basic properties of this effect, wherein the electromagnetic field creates population-trapped atoms and where population-trapped atoms produce matched pulses
