Nd:Ce:YAG Crystals for small laser range finder and laser medical instrument applications
Nd:Ce:YAG is an excellent laser crystal for water-free and air-cooled solid lasers, and is widely used in small laser rangefinders and laser medical instruments. Compared with the traditional Nd:YAG, the co-doped Nd,Ce:YAG crystal has the advantages of high output energyand low laser oscillation threshold. Compared to Nd:YAG, the double-doped Nd,Ce:YAG crystal realizes better utilization of the pump energy and higher laser energy output.
