What type of water is generally used in laser cooling systems?

In laser cooling systems, distilled water is preferred because it is free from impurities and minerals that could interfere with the operation of the equipment. Impurities present in tap water, mineral water, or spring water can lead to scaling, which may clog the cooling system and reduce its efficiency over time. Distilled water undergoes a purification process that removes dissolved salts and contaminants, making it ideal for maintaining the delicate balance needed in laser cooling applications. Furthermore, using distilled water helps to ensure that the heat exchange process remains effective and that the components of the system are not adversely affected by unwanted substances, thus prolonging the life of the equipment and enhancing performance.
