Abstract

The presence of mosaic blocks in ruby crystals has a negative effect on lasing of the rods studied. It has been also found that the low-temperature maximum (Tm=420 K) observed in the samples diffuses when mosaic blocks or strains appear in a crystal. The results also allow to expect that the thermoluminescence can be successfuly used in evaluation of the quality of ruby crystals utilized in laser technology
