Helium Helium is a colorless, odorless, and inert gas commonly used in laser technology, including laser engraving systems. In laser engraving, helium is sometimes employed as a cooling medium to dissipate heat generated during the engraving process. Helium's low density and high thermal conductivity make it effective for heat transfer and cooling, helping to prevent overheating of laser components and ensuring stable and efficient engraving operations. Additionally, helium can be utilized in gas lasers, such as helium-neon (HeNe) lasers, as the active medium for generating laser light. |
