<?php
	//somewhere in a controller
	public function check(){
		$view = &$this->getView('response','raw');
		$view->response = 'OK';
		$view->plain();
	}
?>

In your ajax call use the following base URL:

index.php?option=com_mycomponent&format=raw&

Then append the right controller & task parameters to the url, like:

index.php?option=com_mycomponent&format=raw&controller=mycontroller&task=check
