Nd-Doped Potassium Gadolinium Tungstate Nonlinear crystals The efficiency of Nd:KGW lasers is 3–5 times higher than the one of Nd:YAG lasers. Nd:KGW laser medium is one of the best choices ensuring effective laser generation at low pump energies (0.5 – 1 J). These crystals supplied by EKSMA OPTICS feature high optical quality and great value of bulk resistans for laser radiation. Laser crystals Nd:KGW crystals are low lasing threshold, highly efficient laser ma­erial exceptionally t suitable for laser rangefinding appli­cations. physical and laser properties Chemical formula Lattice...
