Integrated intracavity quasi-phase-matched second harmonic generation (QPM-SHG) has been demonstrated in a periodically domain inverted Nd:LiTaO{sub 3} crystal which functions simultaneously as a gain and nonlinear medium. Lasing at 1.082 {mu}m and simultaneous QPM-SHG at 541 nm has been established by pumping near 806 nm. The effect of doping on the domain reversal voltage of LiTaO{sub 3} and the photorefractive effect have also been investigated. It is found that optical damage can be avoided by heating above 80{degree}C. {copyright} {ital 1997 American Institute of Physics.}
