OPTICAL LASER MATERIAL AND PRODUCTION METHOD THEREOF Russian patent published in 2011 - IPC H01S3/14 B82B1/00 

FIELD: physics.

SUBSTANCE: laser material contains solid-state nanoparticles in an inert medium which is transparent for the optical range. The nanoparticles in the material is dielectric or semiconductor material which is activated with luminescent ions. The nanoparticles have size which is smaller than the luminescence wavelength and are uniformly distributed in a solid isotropic dielectric inert medium. The ratio of the refraction index of the nanoparticles n_cr to the refraction index of the inert medium n_med is in the range of (1.01 - 3.5). Volume ratio of the nanoparticles in the medium is equal to (0.001 - 0.7), and the material is characterised by long mean life of the upper laser level τ^nano _rad.

EFFECT: improved characteristics of laser generation and light amplification.
