• We report the design of a room-temperature (RT), continuous-wave (cw) Cr4+:Y3Al5O12 (Cr4+:YAG) double-clad crystal fiber (DCF) laser grown by a codrawing laser-heated pedestal growth technique using a steady-state lumped model with a Lagrange multiplier optimization method. We demonstrate that the proposed optimization algorithm can provide an efficient and direct approach to analyzing both fiber structure and bulk medium in terms of practical application requirements. The simulation results reveal that Cr4+:YAG DCF lasers offer advantages over bulk lasers in terms of low-threshold lasing and high efficiency, which are essential for their use in optical communication systems.
