Lasing properties of neodymium-activated lanthanum beryllate

An investigation was made of the lasing properties of a lanthanum beryllate (La₂Be₂O₅) crystal activated with neodymium ions. Measurements were made of the lasing line widths under freerunning and Q-switched conditions. The optimum concentration of neodymium ions was determined. An investigation was made of the free-running parameters in lanthanum beryllate and it was found that the differential lasing efficiency is higher than that in YAG.
