Problems solved by technology

[0003] The purpose of the present invention is to provide a rotary water absorber for the problem that the temperature of the light-receiving surface of the absorber is too fast and too high due to the untimely heat dissipation in the current traditional absorber, which even causes the absorber to be damaged by irradiation. The pool, using the chopping method, converts the plane absorption of light energy into a space absorption mode, which reduces the heat value absorbed by the heated surface of the absorption pool per unit time, and at the same time, the heat deposited on the rotor is taken away in time by flowing water , thus improving the peak absorbed power value and working time of the absorption pool

Embodiment 1

[0032] see Figure 1-3 , during the debugging process of laser equipment, an absorption pool is required as a light energy absorption device; with the development of laser technology, the laser beam is developing towards high power and small diameter, and the density of the laser beam to the target is continuously increasing. Most of the traditional absorption pools use planar absorption , but the heat dissipation performance is poor; because the heat dissipation is not timely, it may cause the temperature rise of the light-receiving surface of the absorption pool to be too fast, the temperature rise is too high, and even cause the absorption pool to be damaged by irradiation.

[0033] Based on the problem that most of the traditional absorption pools adopt planar absorption structure and poor heat dissipation, a rotating water-through absorption pool using space absorption is proposed, including:

Abstract

The invention discloses a rotary water-passing absorption cell which comprises an absorption cell body, and a rotor capable of rotating is arranged in the absorption cell body; the rotor rotates to enable light beams entering the absorption cell body to irradiate different positions of the rotor; along with the continuous rotation of the rotor, the irradiation position of the light beam on the rotor is continuously changed, the effect of sufficient absorption is realized, and the absorption capacity is stronger; a plurality of rotors are arranged in a staggered mode, a plane absorption mode of light beam energy is converted into a space absorption mode, and the value of heat absorbed by a single absorption spoke in unit time is reduced; meanwhile, heat deposited on the absorption spokes is taken away in time through flowing water, so that the peak absorption power value and the working duration of the absorption cell are improved; the rotary water-passing absorption cell has unique advantages in energy measurement of high-power and long-time light-emitting intense laser; the rotary water-passing absorption cell is simple in structure and low in manufacturing cost.
