Morphology of selected multicomponent garnet laser crystals grown by micro-pulling-down method

Popis výsledku v původním jazyce

We have prepared the Tm-doped, Ho-doped and Tm,Ho-codoped multicomponent garnet single crystals with different dopant concentrations by the micro-pulling-down method using two types of crucibles. One was a classical crucible with 3 mm diameter circular shaped die with one 0.5 mm capillary. The crystals could be grown well without cracks or any visible inclusions. However, observations with a microscope under polarized light showed significant inhomogeneities, deteriorating the optical properties and laser action of the samples. Therefore, we have changed the crucible design in a way that the 3 mm diameter die included a 2 mm diameter orifice enabling better contact of the melt and the emerging crystalline phase. Such a design led to the crystal homogeneity improvement and the resulting positive influence on the optical properties.
