A new approach to the design of Q-switched solid-state lasers is proposed that offsets heating loads by anti-Stokes fluorescence. In this ideal system, the pump will cool the gain media when the Q switch is off and removes the thermal loads that are generated by the laser pulse when the Q switch is on. The algebraic equations and analytic expressions are derived from the set of coupled rate equations and the requirements for Q-switched radiation balance. Numerical simulation of Yb-doped potassium gadolinium tungstate is provided as an example. Very high average power lasers with 1 kHz repetition rate should be possible under ideal conditions.
