Abstract

The Cr:LiSAF (Cr-doped LiSrAlF₆) laser material is currently being studied and employed in many types of laser systems, such as flashlamp-pumped oscillators and amplifiers, femtosecond regenerative amplifiers, diode-pumped minilasers, alexandrite laser- pumped systems, and Ar-ion laser-pumped self-mode-locked oscillators. While researchers certainly require a basic knowledge of the parameters that characterize the Cr:LiSAF material operating under 'normal' conditions (e.g., the emission cross section, storage time, dn/dT, etc.), they now also need to better understand the natural limits encountered by the material in optimized or novel laser systems. In particular, three areas will be addressed including, firstly, the pump-induced Auger upconversion mechanism, which entails the annihilation of pairs of Cr³⁺-excited states. Secondly, the thermomechanical properties of Cr:LiSAF will be reported and compared to other materials. Lastly, the results of assessing the durability of Cr:LiSAF at various temperatures, and for water/ethylene glycol solutions, will be addressed and compared to values characterizing common crystals and glasses.
