Popis:	Spectroscopic measurements on Pr 3+ -doped Gd 2 SiO 5 and Y 2 SiO 5 crystals were performed. Cross-sections of excited-state absorption (ESA) from the 3 P 0 level of Pr 3+ were estimated in both crystals. Stimulated emission in the red spectral region on the 3 P 0 - 3 F 2 transition was detected in Pr 3+ :Gd 2 SiO 5 . Poor pumping efficiency due to the strong ESA prevents lasing from the 3 P 0 level in both silicates.
