The effect of Nd concentration on 1064 and 946-nm emission of Nd:YAG lasers under continuous-wave Ti:sapphire pumping

摘要

In this paper, we discuss and demonstrate the benefit of using the direct pumping at 885 nm of concentrated Nd:YAG single crystals and ceramics for construction of efficient continuous-wave (CW) solid-state lasers. By using a proper design of the active material and of the laser resonator, slope efficiencies in absorbed power of 79% is demonstrated under end pumping by Ti:Sapphire laser.
