Laser Characteristics of Neodymium-Doped Lithium Germanate Glass.

摘要

The spectroscopic characteristics of Nd-doped lithium germanate glass are compared to those of Nd-doped silicate glasses;the laser characteristics of Nd-doped lithium germanate glass are compared to the corresponding properties of Nd-doped glass and YAG samples. The Nd-doped lasers were end pumped using the 5145-A output of pulsed argon ion lasers and oscillated at about 1.06micrometer at room temperature. This technique enables a precise determination of the pump energy required to reach the oscillation threshold. Threshold energy,output power,spiking,fluorescent conversion efficiency,laser rod losses,and stimulated emission cross sections at 1.06micrometer are compared. Stimulated emission cross-section values of the Nd:lithium germanate glass obtained by two methods are presented. (Author)
