摘要

Simultaneous red and blue light generation in an LiTaOs crystal with a double grating structure is reported for the first time. The double grating consists of two separate domain reversal sequences (superlattices) in seriesand is fabricated by the field poling technique at room temperature. Using a picosecond 532 nm laser as a pump source, the red light at 631 nm and blue light at 460nm are generated at the same time. A possible applicationof the superlattice crystal is presented. X
