Laravel php artisan serve to mimic HTTPS

You can use ngrok for that

php artisan serve
cd <path-to-ngrok>
./ngrok http localhost:8000

https://ngrok.com/

Laravel uses the in-built PHP5.4 development server php -S (http://php.net/manual/en/features.commandline.webserver.php) for it's artisan serve command (see Illuminate\Foundation\Console\ServeCommand). This only supports plain HTTP, so no, this isn't possible. Your best bet would be to use a Vagrant box set up to work with SSL/TLS.
