Abstract：

A　self-adaptive　laser　based　on　a　diode　bar　side　pumped　Nd:　YVO4　slab　with　opened-loop　reciprocal　cavity　completed　by　dynamic　holographic　gratings　is　created.　The　output　power,　optical-to-optical　efficiency,　frequency　spectrum　and　spatial　characteristics　of　the　generated　beam　are　examined.　Compared　with　similar　structure　of　traditional　laser　oscillator,　the　holographic　gratings　are　exist　in　the　opened-loop　reciprocal　cavity　and　the　obvious　modulation　of　the　transverse　mode　and　longitudinal　mode　is　observed.　A　high　spatial　quality　beam　(M2
