Thin-disk athermal laser system

We present a theoretical scheme for Yb³⁺-doped high power radiation-balanced (athermal) thin-disk laser system. This high power laser system consists of several thin disks operating athermally. Athermal amplification is achieved by the balance between heat generated during the amplification process and laser cooling with anti-Stokes fluorescence in the system of active Yb³⁺ ions doped in a KGW host. For athermal operation the pump power has to be distributed properly in the system of several thin disks.
