Model A-25L is a 25 Watt CW sealed co2 laser tube made by Surgilase from mid 80's to about 2000.  They are 25 W CW tubes and the 40 W mark written on it is the absolute maximum possible output that must be written on the tube due to regulations.  They are almost always used in medical systems for surgery and gynecology.  They work with a negative (-ve) polarity high voltage power supply that must deliver an ignition voltage of about 25 kV and then run CW at about 12 kV at 20 mA.  They need water cooling at about 1 liter per minute. 

The output is through a ZnSe partial reflector and the rear mirror is a Silicon total reflector.  They have a life time of about 5 to 8 years and then can be refilled with fresh gas to run like new.  The optics may sometimes need replacement too. 

There are many of them still in use all over the world.
