Provided is a thermal energy network system including: a first thermal station that stores first thermal energy using a first heat source and supplies the first thermal energy to a first demand source used for residence or commerce; and a second thermal station that stores second thermal energy using a second heat source and supplies the second thermal energy to a second demand source used for industry, wherein the first thermal station and the second thermal station manage a base load of a thermal energy network, and the first thermal energy and the second thermal energy are transferred between the first thermal station and the second thermal station as needed.

Thermal energy network system

A method for controlling phases of beams to make relative phases of the beams '0 ' in a beam splitting amplification laser using a stimulated Brillouin scattering phase conjugate mirror. A procedure of making a phase difference between laser beams reflected from the phase conjugate mirror '0' comprises a first step of inputting laser beams reflected from the phase conjugate mirrors to a light detector through light path converter a second step of using one of the reflected laser beams as a reference laser beam and making the reference laser beam interfere with another reflected laser beam; and a third step of detecting the interference result and finely driving piezoelectric element to control the positions of the reflectors, to thereby make a phase difference between the become &#x201c;0&#x201d;.
