Laser processes to enable robust, miniaturized beam sources for quantum technology

Phys · · 1363 words · By Petra Nolis

The HiPEQ project, a consortium of industry and research partners including Fraunhofer ILT, has developed miniaturized and robust laser beam sources for quantum technology. The project focused on growing high-purity (TbxLu1-x)2O3 isolator crystals and utilizing selective laser-induced etching (SLE) to create precise glass packaging modules.
