The Visible Beam you see in some Markers today does absolutely NOTHING but drain batterries faster. it's a FACT that Infrared is invisible to the naked eye. However if seeing an actual beam is that important to anyone, just take a digital camera and look into the breech of ANY Break-Beam Marker. You can now see the beam or "Laser" as you put it.
About the only thing a visible beam is good for is to indicate when the eyes are broken. if they're Broken... No "Laser".
