Nd:KGW crystal is very efficient laser material suitable for laser range detection and measuring applications. Compared to Nd:YAG lasers, Nd:KGW lasers has several times higher effieciency. Nd:KGW laser crystal is one of the best choice ensuring effective laser emission generation at low pump energies up to 1 J. These crystals can produce high optical quality with great value of bulkness resistance to laser radiation.
Optola offers standard Nd:KGW crystals with doping concentrations 3% – 8%.
Standard diameters of up to 20 mm with length up to 100 mm.
Non-standard Nd:KGW crystals are available upon request.
