Neodymium doped Yttrium Aluminum Garnet
Neodymium doped Yttrium Aluminum Garnet (Nd3+ :Y3A15O12) laser crystal is the most wildly used in industrial, medical and scientific applications. Its main advantages are: low threshold, high efficiency, low loss at 1.064 µm, as well as high optical quality, good thermal conductivity and thermal shock characteristics, stable chemical and mechanical properties, which make Nd:YAG as the most suitable and commercial laser material for all types of solid-state lasers.
Our company grows crystals by the method of Horizontally Directed Crystallization with dimensions up to 250x180x25mm.
