I do not know much about lasers.  I cannot test it as I don't have the key to engage power source.   It came from government lab.    This is the rare Krypton-Ion Powered Laser (keep Superman away).  

Missing screws to hold cover on.  

According to a data check sheet inside the laser it is:   7 Watts / 570 volts / 50 amps 

this is about 7-8 feet long and weights over 100 pounds.  And guess what?  We will ship this to you for free.  We will put it on a pallet and shrink wrap this and probably send it freight.
