We present an overview of pump-induced lensing effects in end-pumped Alexandrite lasers. The dioptric lens power is measured for a diode pumped Alexandrite laser using a Shack-Hartmann wavefront sensor under both non-lasing and lasing conditions. Under non-lasing conditions, the lens dioptric power is measured for two pump sizes and in both cases is found to be nearly linear with respect to the absorbed pump power. Under lasing conditions the lens dioptric power is up to 60% weaker. Good agreement is found between the non lasing and lasing experimental results using a model based on a combined lens consisting of a thermal lens, and a population lens arising from the electronic component of the refractive index. Fitting parameters using an analytical model for the two pump sizes are also found to be consistent. Values for the difference in excited to ground state polarizability are obtained and found to be consistent with prior measurements for Alexandrite and other Chromium-doped gain media.
