Abstract

Spectroscopic and laser properties of Cr,Nd:GGG and Nd:YAG crystals in the 1.3 - 1.45 micrometers wavelength range have been compared. Flashpumped Cr,Ce,Nd:GGG laser operating at 1.331 micrometers with total efficiency up to 3% and average output power of 65 W has been developed. For the first time to our knowledge oscillation at 1.4237 micrometers wavelength in Cr,Nd:GGG crystal have been obtained. Output energy of 2.3 J at this eyesafe wavelength with total efficiency of 1.23% have been obtained for flashpumped Cr,Ce,Nd:GGG laser in free-running mode. Average output power of 21.6 W at 13 Hz repetition rate have been achieved. Cr,Nd:GGG crystals advantages for 1.4 micrometers lasing compared to Nd:YAG crystals are discussed.
