Abstract

Having a larger stimulated emission cross section and stronger fluorescence emission, a laserdiode (LD) pumped Nd: YVO₄ laser has higher efficiency and power than Nd: YAG laser.Spectral property and CW end-pumped lasing characteristics have been measured on thismaterial. Stimulated emission cross section of 2.5×10^-18cm² for π polarization, slope efficiencyof 48.6% and light to light conversion efficiency of upto 40% for laser rod along a-axiswere obtained.
