Experimental studies were performed on the effect of doping level and diameter of neodymium glass rods and reflectivity of the output mirror on the threshold energy and output energy of the laser. Data are presented of the energy output of glass rods having diameters of 0.25 in, 0.393 in, and 0.5 in and doping levels of 1, 3, and 6 percent neodymium. In most cases, an output mirror reflectivity of 62 gave the highest energy output. Maximum output was obtained with the 1 doping, 0.5 in diameter rod, using a 62 reflecting mirror. Due to pitting of the rods, the data obtained were generally inconsistent and for the most part nonreproducible. Author
