A rotary disk module, having a rotary disk is interposed between a pair of heat sinks each spaced from the rotary disk by a gap. A motor is installed for driving the rotary disk to rotate. The gaps are filled with cooling medium such as helium, water or liquid nitrogen to remove the heat generated in the rotary disk by conduction, convection or evaporation. The rotary disk may be fabricated from various materials depending on the intended applications of the module, and the heat sink surfaces are preferably fabricated from materials with higher thermal conductivity. The rotation of the rotary disk allows the regions on which an optical pump radiation is delivered to be separated from the regions from which an optical radiation is extracted. In addition to improved heat dissipation effect, the rotation of the optical disk allows multiple directions of pump energy or multiple sources of pump energies and/or multiple beams of optical radiation to be applied and extracted simultaneously.
