Abstract

We deal with new laser materials, substituted gadolinium gallium garnets or lanthanum hexaaluminates, doped with Nd 3 + or Cr3 +. We summarize the main spectroscopic properties which may be favorably compared to that of already known efficient high average power laser materials (YAG:Nd3 +) or tunable solid‐state lasers (GSGG:Cr3 +). The possibility of improved laser efficiency by Cr3 + → Nd3 + energy transfer in codoped crystals is also studied. More generally, we present the trends in this active research field.
