Abstract

Making use of the double doped (Nd, Ce):YAG crystal rod made by south-west Institute of Technical Physical in the compact repetitive solid state laser, the more increasing laser efficiency at the high surrounding temperature (50 degrees Celsius to approximately 140 degrees Celsius) has been found with the codoped crystal laser than that with the usual Nd:YAG crystal laser. The energy transfer mechanism between Ce³⁺ and Nd³⁺ was studied at a higher temperature (100 degrees Celsius). The increasing radiative energy transfer was observed at the high surrounding temperature than at the normal room temperature. This means that the radiative energy transfer mechanism between Ce³⁺ and Nd³⁺ is much more improved at the higher surrounding temperature than that at the room surrounding temperature.
