Performance of 532 nm generation by PP-LBGO device was investigated by pulsed 1064nm doubling. It was realized non-walk-off 532nm generation at room temperature by PP-LBGO. The temperature tolerances are approximately 3 to 4 times wider than those of LBOs. Since coercive field of LBGO is 3.8 kV/mm and QPM periodicity is wider around 20 micron, it could be possible to realize high power 532 nm generation with large aperture PP-LBGO device.
