Laravel routes with slash /

I use Laravel 5.1.

at route I have:

Route::get('/getVoucherRld', 'LiveController@getVoucherRld');

Route::get('/test/getVoucherRld', 'TestController@getVoucherRld');

both getVoucherRld functions are the same but when I try to run then with ajax

function from LiveController works fine but function at TestController just retunr me white screen?

I think the issue is with the route but why? Does anyone have the same issue?
