    It is more like technology now. You need a good absorber which energy level equal to a bad absorber. Good absorber absorbs the radiation to get a electron to the energy. This electron collides with a bad absorber and excites the other one. In this way bad absorber goes on getting excited. If sufficient excitation occurs then then de-excited the bad absorber. You get the laser. You need He and Ne, carbon oxygen etc combination.
