We　report　the　experimental　observations　of　the　second-　and　third-order　hybrid　intensity　noise　correlation　and　intensity　difference　squeezing　among　two　different　multi-order　nonlinear　fluorescence　(FL)　and　two　FL　signals　as　well　as　one　of　pair　of　phase　conjugate　four-wave　mixing　in　a　Pr3+:Y2SiO5　crystal,　respectively.　The　degrees　of　the　correlation　and　squeezing　as　well　as　the　sharp　and　broad　peaks　are　studied　by　changing　the　polarization　of　laser　fields　and　gate　position　in　Lambda-type　three-level　systems.　We　observed　the　multi-channel　hybrid　intensities＇　correlation　among　the　composite　and　coexisting　signals,　which　turn　out　to　be　positive　and　negative　for　the　cases　without　and　with　Autler-Town　splitting　of　FL,　respectively.　A　wide　broad　peak　and　a　high　sharp　peak　are　observed　with　respect　to　the　degrees　of　correlation　and　polarization　state　controlled　by　wave　plates.　Such　results　may　find　potential　applications　in　optical　transistor　and　optical　hybrid　communications.　Published　by　AIP　Publishing.
