Defining the optimal gradient doped Yb^(3+):YAG disk for room and low temperature diode pumped solid-state laser operations

We propose a general methodology to define the optimum doping ion volume distribution required for an efficient solid-state laser amplifier. This approach is illustrated in the context of two experimental diode pumped Yb:YAG amplifiers operating at 300 and 160 K. Processing of such tailored gain media is now possible through horizontal direct crystallization.
