More Information
Summary:The utility model relates to a device for measuring laser pulse energy, which is used for detecting the laser pulse energy, and comprises a sampling and holding module used for sampling laser pulses;the processing module is used for determining the current laser pulse energy value of the laser pulse to be measured; and the comparison module comprises an analog signal with laser pulse energy and is used for receiving the current laser pulse energy value and comparing the current laser pulse energy value with the laser pulse energy of the analog signal so as to determine the laser pulse energylevel of the laser pulse to be measured. The utility model also provides a light energy detection circuit. The device for measuring the laser pulse energy is small in size, low in power consumption and flexible to use, and can detect short pulse signals with pulse duration of 1 ns to 1 ms; the circuit for measuring the laser pulse energy realizes real-time detection of the laser pulse energy. 本实用新型涉及一种测量激光脉冲能量的装置，用于对激光脉冲能量
