Engineers Create New Tunable Laser Materials

Engineers doped alumina (Al2O3) crystals with neodymium (Nd) ions to develop a new laser material capable of emitting ultrashort, high-power pulses. Their approach to materials processing resulted in a Nd-Al2O3 laser gain medium that has 24X higher thermal shock resistance than one of the leading solid-state laser gain materials.

Materials processing tricks enable engineers to create new laser material

By doping alumina crystals with neodymium ions, engineers have developed a new laser material that is capable of emitting ultra-short, high-power pulses — a combination that could potentially yield smaller, more powerful lasers with superior thermal shock resistance, broad tunability and high-duty cycles.
