Abstract

The invention provides a conical cavity type high-energy laser total-absorption energy meter. The energy meter comprises an absorber, a thermocouple sensor, an absorber support, a barrel-shaped insulator, a data acquiring system and a shell, wherein the absorber is made of a high-purity graphite material and has a cone structure; a conical hollow cavity is formed in the absorber; the absorber support is fixedly connected with the shell in a threaded manner; the middle and the bottom of a cone of the absorber are arranged on the support; the insulator is arranged in the shell; the thermocouple sensor is adhered to counter bores in the surface of the absorber; the distance between the bottom of each counter bore in the absorber and the outer surface of the absorber is 40% of the thickness of the wall of the absorber; the counter bores are equidistantly formed along the cone busbar direction and the direction perpendicular to a busbar; and the distance between two optional counter bores along the cone busbar direction is smaller than the length of the cone busbar of the absorber by 10%. By using the conical cavity type high-energy laser total-absorption energy meter, the high-energy laser energy measuring precision can be obviously improved; and the testing capability of the high-energy laser total-absorption energy meter is improved.

Description

technical field [0001] The invention belongs to the field of high-energy laser energy measurement, in particular to a cone-cavity high-energy laser total absorption energy meter, which is suitable for high-energy laser energy measurement. Background technique [0002] There are two main methods for high-energy laser energy measurement: the first method uses spectroscopic sampling, and then uses a low- and mid-range power energy measurement device to measure the sampled laser energy, and finally according to the measurement results of the low- and mid-range power energy measurement device and the spectroscope The splitting ratio is used to calculate the total laser energy; the second method directly uses the energy measuring device to measure the total laser energy, which requires the measuring device to absorb almost all the laser energy. This type of device is usually called a total absorption measuring device. The first method adopts the method of indirect sampling measure...
