Krok, P C

The temperature derivative of refractive index (dn/dT) was determined for samples of laser window materials at 10.6 micrometers. A dual-beam ratiometric photometer was used to investigate fringe patterns which result from multiple internal reflection interference within the sample. One sample of CVD ZnSe and three samples of single crystal KCl were examined. A unique sample holder was constructed so temperature changes of the sample could be closely controlled and monitored.
