laser过程的熵演化规律

Entropy evolution law in a laser process

Jun-hua Chen, Hong-yi Fan

摘要:

利用纠缠态表象,通过求解描述激光过程的主方程的Kraus算符,首次得到了激光过程的熵变规律。熵的行为取决于激光过程中增益和阻尼的竞争。得到了光子数演化公式。

英文摘要:

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.
