Fundamentally recent growth monocrystals of YVO4/Nd3+:YVO4 totally
differ from analogous
bonded crystals by lack of junction. This ensured that our combined crystals are
able to stand with considerably higher energy loads, without loss in quality.
As is well known bonded crystals obtained by joining of undoped and Nd3+-doped
crystals using thermal diffusion have got an optical loss on the welding border
of two parts, but they lead to
decreasing of laser efficiency and cracks can appear on the border at certain
light load that contribute to destruction of optical rod.
Under testing our permanent laser
beam research technology partners growth
monocrystals have output generation characteristics 10-15 % higher than
common combined crystals
