EXCITED EMISSION AND SELF-FREQUENCY-DOUBLING EFFECT OF Nd_(x)Y_(1-x)Al_(3)(BO_(3))_(4) CRYSTAL

摘要

Using dye laser as pumping light source,we have first realized on NYAB crystal the laser self-frequency doubling run from 1.06μm to 0.53μm.The threshold energy is less than 4mJ;conversion efficiency is 6.2%,and the self-frequency-doubling green light output energy is 2.5mJ.
