Abstract : A study of the spectroscopic and laser properties of the crystal erbium-and chromium-doped yttrium scandium gallium garnet (Er, Cr:YSGG) has been carried out. The absorption spectra form 300-1700 nm and the emission spectra in the regions around 800, 1600 and 2800 nm have been measured, along with the kinetics of emission and decay under pulsed excitation. Energy levels of the erbium ion have been determined. Analysis of the data shows that energy transfers from excited chromium ions to erbium ions with near-100% efficiency. The 2800-nm-region laser performance of Er,Cr:YSGG, under flashlamp pumping conditions has been observed and found to be superior in some aspects to other erbium-doped crystals.
