Paper Abstract

We investigate the inversion dynamics in Nd:Cr:GSGG laser rods as a function of pumping frequency in order to optimize Nd:Cr:GSGG Q switched lasers for rapid time to fire applications. By frequency filtering the pump light to the Nd:Cr:GSGG rod and measuring the florescence from the rod, we determine the dynamics for different excitation processes in the laser (i.e. direct excitation of the Nd ions or indirect excitation via Cr ions). We also measure the flashlamp pulse shape using various spectral filters This combination of measurements help us understand the processes contributing and limiting the efficiency of Nd:Cr:GSGG lasers when the lasers must fire on a short time scale.
