Nonlinear　Raman　forward　scattering　of　an　intense　short　laser　pulse　with　a　duration　shorter　than　the　plasma　period　propagating　through　a　homogenous　collisional　nonextensive　distributed　plasma　in　the　presence　of　a　uniform　magnetic　field　perpendicular　to　both　the　direction　of　propagation　and　electric　vector　of　the　radiation　field　is　investigated　theoretically　when　ponderomotive,　relativistic,　and　collisional　nonlinearities　are　taken　into　account.　The　governing　equations　for　nonlinear　wave　in　the　context　of　nonextensive　statistics　are　given,　the　nonextensive　coupled　equations　describing　the　nonlinear　Raman　forward　scattering　instability　are　solved　by　the　Fourier　transformation　method,　and　the　growth　rate　of　the　nonlinear　Raman　forward　scattering　instability　is　obtained.　The　results　in　the　case　q　-＞　1　are　consistent　with　those　in　the　framework　of　the　Maxwellian　distribution.　It　is　found　that　the　instability　growth　rate　first　decreases　on　increasing　electron　thermal　velocity,　minimizes　at　a　critical　thermal　velocity,　and　then　increases　steeply;　the　critical　temperature　dependents　on　the　nonextensive　parameter,　and　the　greater　nonextensive　parameter,　correspond　to　the　greater　critical　temperature;　when　the　thermal　velocity　of　electron　is　less　than　the　critical　speed,　the　instability　growth　rate　is　found　to　be　enhanced　as　the　nonextensive　parameter　increases;　but　when　the　thermal　velocity　is　greater　than　the　critical　speed,　the　instability　growth　rate　decreases　on　increasing　the　nonextensive　parameter.　(C)　2015　AIP　Publishing　LLC.
