A particle diameter acquisition device includes an intensity distribution acquisition unit configured to acquire an intensity distribution of scattered light scattered from a multi-phase flow including dispersed phase at the time of irradiating the multi-phase flow with irradiation light, an attenuation gradient acquisition unit configured to acquire an attenuation gradient in the intensity distribution on the basis of the intensity distribution of the scattered light, a concentration acquisition unit configured to acquire a concentration of the dispersed phase in the multi-phase flow, a database configured to store intensity distribution data which is an intensity distribution of scattered light for each particle diameter and concentration of a dispersed phase, and a particle diameter acquisition unit configured to acquire a particle diameter of the dispersed phase on the basis of the acquired attenuation gradient, concentration, and intensity distribution data with reference to the intensity distribution data.

Particle diameter acquisition device, particle diameter acquisition system, and particle diameter acquisition method

This solid laser amplification device has: a laser medium part that has a solid medium, into which a laser light enters from an entrance part and from which the laser light (L) is emitted to the outside from an exit part, and an amplification layer, which is provided on the surface of the medium, receives the laser light in the medium, and amplifies and reflects said light toward the exit part; a microchannel cooling part that cools the amplification layer; and a thermally conductive part that is provided so as to make contact between the amplification layer and the cooling part and transfers the heat of the amplification layer to the cooling part.

Solid laser amplification device

A solid laser amplification device having a laser medium that has a solid medium, into which a laser light enters and from which the laser light is emitted, and an amplification layer, provided on the surface of the medium, receives the laser light in the medium, and amplifies and reflects the light toward the exit; and a microchannel cooling part that has a plurality of cooling pipelines, into which a cooling solvent is conducted and which are arranged parallel to the surface of the amplification layer, and a cooling surface, at the outer periphery of the cooling pipelines and attached on the surface of the amplification layer, the microchannel cooling part cooling the amplification layer. The closer the position of the cooling pipeline to a position facing a section of the amplification layer that receives the laser light, the greater the cooling force exhibited by the cooling part.
