Measurement device, with step-shaped cone, absorbing all energy of high-energy laser

The invention provides a measurement device, with a step-shaped cone, absorbing all energy of a high-energy laser. Light enters an absorbing cavity from the entrance of an energy meter, arrives in a reflection body in an incident mode and can be absorbed by the absorbing cavity after being reflected by the reflection body, and temperature rise of each region of an absorbing body is measured by a temperature measurement component and is combined with quality and specific heat of combustion to work out the energy increment of each region. Water channels are formed in the wall of the reflection body and the wall of the absorbing body respectively, and water is filled into the water channels to bring away most heat. Laser energy brought away by the water can be indirectly worked out through a water circulation component according to temperature changes and flow during the period from the time when the water enters the absorbing body and the reflection body to the time after the water departs from the absorbing body and the reflection body. The total energy of increment lasers can be worked out by a data collecting component according to energy measured by the temperature measurement component and energy measured by the water circulation component. Because the step-shaped emitting cone serves as the reflection body, the absorbing body is of a cylindrical structure, the effect caused by low laser induced damage thresholds, temperature measurement accuracy, heat loss and light energy escaping in the prior art is avoided, and the measurement device has the advantages of being high in efficiency ratio and testing efficiency and the like.
