Sometimes I don't know the difference between the two. Can someone explain it??

      1. Generally, power is used as the parameter for continuous laser and energy is used as the parameter for pulse laser.
      
      2. Suppose a pulse laser emits 10 pulses (repetition rate 10Hz) in one second, each pulse is 100mJ, and each pulse lasts for 10ns. Then the pulse energy is 100 mJ. The peak power is 100 mJ/10 ns=10000000 W. The average power is 100 mJ * 10 Hz=1 W
      
      For continuous laser, the average power is generally used as the parameter.

        3. The higher the frequency is, the higher the pulse power is, and the higher the energy is. The pulse laser is mostly small power. Continuous power is mostly high power.
