A new laser cooling method is disclosed in which materials in different physical states are laminated about the laser body. Specifically, thin gas layer is used as a heat conductor in thermal contact with the laser body. In contact with the gas layer is a high thermal conductivity solid which is also optically transparent at the pump wavelength. This material, in turn, has its opposite face or edges, or both, in contact with a liquid coolant. Thus, there is provided a cooling method in which gaseous and solid state materials act as heat conductors for liquid cooling the laser apparatus.
