LASER SUBSTANCE Russian patent published in 2021 - IPC H01S3/213 

FIELD: electronics.

SUBSTANCE: invention relates to the field of quantum electronics, in particular, to solid-state organic lasers. A large amount of polymer laser-active media based on acrylates and methacrylates currently exists, doped with organic compounds in order to obtain laser generation, emitting in the optical spectral range. The claimed laser substance comprises di(phenyl-5-oxazolyl-2)-1,4-benzene, polymethyl methacrylate, and additionally comprises (1,3,5,7,9,11,13,15-octa(propyl methacrylate)pentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane) at the following ratio, wt.%: di(phenyl-5-oxazolyl-2)-1,4-benzene - 0.04; (1,3,5,7,9,11,13,15-octa(propyl methacrylate)pentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane) - 8; polymethyl methacrylate the rest.

EFFECT: increase in the operating life of the solid-state organic laser medium emitting in the blue spectral range, and reduction in the pumping power density with maintained light emission conversion efficiency (performance coefficient).
