Parasitic oscillations, absorption, stored energy density and heat density in active-mirror and disk amplifiers.
We present detailed calculations of the absorption, stored energy density, and heat density distributions for these commercial laser glasses of current interest (silicate-ED-2, phosphates-EV-2, LHG-5). The form of the stored energy density distribution is shown to be important in the consideration of parasitic oscillations in active-mirror and disk amplifiers. In active-mirror amplifiers, the application of multilayer dielectric coatings has been found not to affect the threshold for bulk parasitic oscillations. Due to the unique geometry of active mirrors, amplified spontaneous emission rather than parasitics is found to limit energy storage ultimately.
