Paper Abstract
We present lasing experiments in index-antiguided (IAG) planar waveguides made of Nd:YAG (refractive index = 1.820)
sandwiched by Terbium Gallium Garnet (refractive index = 1.954). For a core width of 220 μm, we observe fundamental
mode oscillation with maximal 2.62 W output power and 0.109 slope efficiency. An analytical model is developed
taking into account simultaneous index-antiguiding, gain guiding and thermal induced refractive focusing. For a core
width of 400 μm, fundamental mode oscillation is only observed near the lasing threshold, suggesting that the maximally
core width in IAG waveguides for fundamental mode operation depends on the strength of index antiguiding.
