通过对激光的电噪声的测量可以监测激光器的诸多参数和特性，如弛豫频率，谱线宽度，阈值电流，模式跳变及输出光功率是否稳定等。

We can monitor many parameters and characteristics by measuring TEN, such as surge frequency, spectrum width, threshold current, mode jump and stability of output light power.

观察到锁频，相邻模式间的频率跳变及滞后等现象。

The frequency locking, frequency jump between neighboring modes and the hysteresis phenomenon are observed.
