Abstract:	This is a combination of experiments and three-dimensional numerical simulation approachto verify the simulation results of the molten zone shape by experimental data. We study the effect ofCO2 laser heating ring and gravity field deviation caused by the space perturbation on micro-floating zone of LHPG during the fiber growth under comparing similar conditions and changing the inputparameters of simulation. Our preliminary results compared the molten zone shape are satisfied. Theshape of the molten zone (especially the solid-liquid interface) by the asymmetrical heating effect is much larger than the result of gravity field in the simulation results of tilting 3 degrees when thesource rod diameter is below 500 microns. And the influence will decrease rapidly with the source rodscale and diameter reduction ratio reducing.These results will help us with the internal flow of themolten zone analysis and developing LHPG crystal fiber growth along horizontal direction in the future.
