Read More: An exciton-polariton laser based on biologically produced fluorescent protein http://advances.sciencemag.org/content/2/8/e1600666.full "We demonstrate room temperature polariton condensates of cavity polaritons in simple laminated microcavities filled with biologically produced enhanced green fluorescent protein (eGFP). The unique molecular structure of eGFP prevents exciton annihilation even at high excitation densities, thus facilitating polariton condensation under conventional nanosecond pumping." How Lasers Work http://science.howstuffworks.com/laser.htm "Although there are many types of lasers, all have certain essential features. In a laser, the lasing medium is "pumped" to get the atoms into an excited state. Typically, very intense flashes of light or electrical discharges pump the lasing medium and create a large collection of excited-state atoms (atoms with higher-energy electrons)." The first laser http://www.press.uchicago.edu/Misc/Chicago/284158_townes.html "When the first working laser was reported in 1960, it was described as "a solution looking for a problem." But before long the laser's distinctive qualities-its ability to generate an intense, very narrow beam of light of a single wavelength-were being harnessed for science, technology and medicine." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!
