Abstract
A scheme for realizing a photon number amplifier by use of a high-quantum-efficiency photodetector and a number-state semiconductor laser is analyzed. It is found that the photon number amplifier is not significantly limited by the electronic amplifier noise or by the laser quantum efficiency for input states that are nearly classical.
