It was shown that the identical particles could form coherent states in which the photon emission probability of the superradiant state is a liner function of N2 and N2 (N is the particle number).
结果表明，全同粒子会成相干态，其中超辐射态的光子发射几率是粒子数的平方和三次方的线性函数。
So we can control the population which can trigger the Q-switch by controlling the superradiant convert electrical level in the superradiant detector and then the laser output can be stabilized.

The principle is as follows: The superradiant signal intensities near the axial correspond to certain population during the laser process of the optical pumping.
它的原理是，在脉冲电光调Q激光器的光泵过程中，一定的轴向超辐射强度对应激活介质中一定的反转粒子数。
