Lasers productivity is determined by... a) radiation intensity b) the size of a laser c) the volume of gas in a laser tube

c) the volume of gas in a laser tube

The productivity or performance of a laser is influenced by various factors, but one important factor is the volume of gas in a laser tube. The gas inside the tube plays a crucial role in the laser's operation by amplifying the light and generating the laser beam. Adjusting the volume or pressure of the gas can affect the output power and efficiency of the laser.
