Although may need some.. adjustment, or beam combining to turn into an effective UV laser, as in the non-visible kind. Which would also need some care, attention and preferably some appropriate safety glasses on account of UV not triggering the blink response.
Not sure what response it'd trigger in a RIng piece, other than eventual smoke because I'm assuming it'd have some form of UV filtering or protection to deal with being left in the sun.
