Abstract
A solid state laser whose medium is a strontium aluminum fluoride crystal doped with chromium. This laser medium has a wavelength tuning range centered around 850 nm and the laser gain is estimated to be a factor of 2-3 times higher than that of emerald and alexandrite lasers at room temperature.
