Abstract:A laser diode end-pumped 10at% doped Yb:YAG microchip crystal,type-Ⅰ critical phase-matched LBO crystal,intracavity frequency doubled 525nm solid-stated green laser is reported in the paper.Using one plano-concave resonator,with the pump power of 1.43W,22.3mW TEM00 continuous wave laser at 525nm is obtained.The optical conversion efficiency is 1.5%,and the ellipticity of the output beam is 0.99.The output power of intracavity frequency doubled laser is influenced by intracavity photons density of fundamenta...
