摘要：

The　conversion　efficiency　of　the　second　harmonic　generation　(SHG)　properties　of　Gaussian　and　flattened　Gaussian　beams　(FGB＇s)　is　studied　in　detail.　For　the　first　time,　the　SHG　efficiency　of　the　FGB＇s　versus　the　crystal　lengths,　the　pumping　wave　polarization　ratio,　the　order　of　the　FGB＇s　and　the　pumping　power　intensity　has　been　calculated　by　computer　simulation.　The　theoretical　efficiency　of　SHG　has　been　brought　near　1　in　type　I　when　the　pumping　radiation　is　that　of　FGB＇s.　The　efficiencies　are　78.1%　and　75.4%　as　the　pumped　wave　is　the　FGB＇s　of　type　II　(1)　and　type　II　(2),　respectively.　It　has　been　pointed　out　that　the　highest　SHG　efficiency　was　influenced　by　the　order　and　polarization　ratio　of　the　pumped　FGB＇s　and　the　efficiency　of　the　FGB＇s　is　theoretically　obtained　to　be　higher　than　that　of　the　Gaussian　beam　with　phase　matching　of　type　I　and　type　II.
