How to develop biological laser beam eyes?

Here a laser raptor Pew Pew'ing in its natural habitat and timeline.

(From the Kung Fury movie)

So I want to know how a biological organism can develop to spew laser beams through their eyes. What kind of organs are needed to generate the laser, and are the natural adaptations required to achieve this?

The laser eyes's function is not like Cyclop's from the X-men, but more like laser beams from Superman's eyes where you can switch it off and on.

Preferably they would still have functional eyes to see normally, so no ecolocation, x-ray vision, etc

And as I mention the eyes should be biological and natural, so no genetic engineering or bionic technology involved.
