Ruby laser weaknesses in the lining. Ruby lasers were used extensively in tattoo and hair removal, but are being replaced by alexandrite and s in this application. The ruby laser was the first laser to be made functional. Built by Theodore Maiman in 1960, the device was created out of the concept of an "optical maser," a maser that could operate in the visual or infrared regions of the spectrum. In 1958, after the inventor of the maser, Charles Townes, and his colleague, Arthur Schawlow, published an article in the "Physical Review" regarding the idea of optical masers, the race to build
Cyclops laser filters between each stage and easily achieved terawatt beam powers. Cyclops laser Cyclops was a high-power laser built at the Lawrence Livermore National Laboratory (LLNL) in 1975. It was the second laser constructed in the lab's "Laser" program, which aimed to study inertial confinement fusion (ICF). The Cyclops was a single-beam Neodymium glass (Nd:glass) laser. The Janus laser, a two-beam version of it, was also completed in 1975. The main scientific aims of its construction were for the study of nonlinear focusing effects in high power laser beams, novel amplification techniques (disks of Nd:glass at the brewster angle), spatial filtering
