Abstract
The edge of fundamental absorption in langasite crystal was studied. The energy gap was measured to be 6,5 eV. Using the technique of the second harmonic generation in powdered samples, the value of the quadratic nonlinear susceptibility in langasite crystal was estimated to be 7 times higher than that in quartz.
