1209.4149 (Jun-hua Chen et al.)

Entropy evolution law in a laser process    [PDF]

Jun-hua Chen, Hong-yi Fan
For the first time, we obtain the entropy variation law in a laser process after finding the Kraus operator of the master equation describing the laser process with the use of the entangled state representation. The behavior of entropy is determined by the competition of the gain and damping in the laser process. The photon number evolution formula is also obtained.
