A theoretical analysis is made of the main factors limiting the maximum attainable gains in laser-pumped glasses (/sup 4/I/sub 13/2/--/sup 4/I/sub 15/2/ transition in Er/sup 3 +/ ions) activated with Yb/sup 3 +/ and Er/sup 3 +/ ions. It is shown that, in principle, the spectroscopic and lasing parameters of the glasses make it possible to obtain gains of up to 0.8--1 cm/sup -1/, the main limiting factor being superradiance. Experimental measurements were made of the short pulse gains in phosphate-based glasses activated with Yb/sup 3 +/ and Er/sup 3 +/ ions at the highest possible pumping levels and the results were compared with the theoretical analysis.
