Abstract
oŁ, the laser cross-section and oF, the cross-section derived from absorption and fluorescence measurements through LandenburgFuchtbauer relationship have been estimated for a series of Nd3+containing silicate glasses. A direct correlation between o L and oF for Nd3+ in silicate glasses could be established. A technique has been developed for producing glasses of good optical quality on a small scale over a wide range of composition. Laser rods were cut from glass made by this technique and their cross-sections measured. The laser cross-section varied from 1 x I0-20 em• to 3.2 x I0-20 em•. The rod did not thermally fracture when operated at a repetition rate of 10 p.p.s. with 30J per pulse input power. The results also indicate that the damage threshold is sufficiently high to suggest that this glass may be a viable alternative to CaW04 in a laser range finder.
