An RF laser is still a conventional laser. Instead of a lasing media that is excited with light, it's excited with radio frequency waves. (Light frequency waves and radio frequency waves are the same thing and differing frequencies. Both are electromagnetic radiation)
Output is the same. It's still a highly concentrated beam of light. Still requires mirrors and focusing lenses.
