Abstract:

The laser will be used extensively on the modern battlefield to greatly improve the accuracy of new Army weapon systems. Some examples of applications are laser range finders in the XM-1 tank and other armored vehicles and laser target designators for infrared guided missiles and projectiles such as HELLFIRE and COPPERHEAD. While lasing ability is found in gases, liquids, and solids both crystalline and noncrystalline, the laser preferred in the above Army application, because of its high efficiency and narrow spectral linewidth, is a single crystal of a compound of yttrium oxide and aluminum oxide with small additions of neodymium oxide as the active element.
