Did you know that CO2 lasers are used to create cutting-edge integrated circuits in your mobile phones? Extreme ultraviolet lithography (EUVL) systems use a 30-kW, short pulse CO2 laser focused on a 30 µm liquid tin droplet, repeatedly 50,000 times per second, to produce 250 W of EUV light at a 13.5 nm wavelength. The … Continue reading
Carbon dioxide (CO2) emission lines suitable for laser operation span the 9.2 to 10.8 µm wavelength range. Combinations of carbon and oxygen isotopes yield another 17 molecular species – including the popular 12C18O2 and 13C16O2 configurations. With up to 80 lines for each species, these isotopic molecules fill the spectral gaps of the others and … Continue reading

By the 1970s, the telecommunications industry was increasingly interested in growing single crystal oxides of small-diameter and high-purity due to their advantageous material properties for fiber optical applications. The floating zone technique was the preferred choice, but could not be applied due to inefficient RF heating of the oxides. A solution to this problem was presented … Continue reading
