PHP Soapclient in Laravel 5

I want to use php's built in SoapClient class in laravel 5

I tried using it directly is shows error saying

Class 'App\Http\Controllers\SoapClient' not found.

I tried adding SoapClient in aliases array in config/app.php like this

'SoapClient' => SoapClient::class

Still not working

what should I do?

Thanks in Advance...
