How to php artisan (Laravel) headers?

I launch Laravel server using:

php artisan serve

How in this case to set header:

Header set Access-Control-Allow-Origin "*"

If I dont use Apache?

I tried to add this line into .htaccess:

RewriteEngine On

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    Header set Access-Control-Allow-Origin "*"

But it does not work.
