Nd or Yb-doped potassium gadolinium tungstate (Nd: or Yb:KGd(WO4)2) crystal
Nd:KGW crystals Optolita

Nd:KGW crystals are low lasing threshold highly efficient laser material exceptionally suitable for laser rangefinding applications.

The efficiency of Nd:KGW lasers is 3-5 times higher than that 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 feature high optical quality and great value of bulk resistance to laser radiation.

Existing technology produces single crystals of up to 3 kg, thus allowing reliable and high yield fabrication of round elements of up to 12 mm in diameter and up to 120 mm in length.
