Abstract

Results of observation made on the optical homogeneity of Nd3+ and Pr3+ glass rods by Schlieren method and on near field patterns of the stimulated emission of these glass rods photographed on plates sensitized for infrared radiation show that the oscillation of glass lasers is seriously hampered by striae and that, with Nd3+ glass of homogeneous structure or nearly so, the oscillation begins at the center and at the periphery of the rod. The stria causes the threshold input energy of building up the laser oscillation to become much higher.
