We report a systematic study of AgGaS 2 - and Al-doped GaSe crystals in comparison with pure GaSe and S-doped GaSe crystals. AgGaS 2 -doped GaSe (GaSe:AgGaS 2 ) crystal was grown by Bridgman technique from the melt of GaSe:AgGaS 2 (10.6 wt.%). Its re

We grew nonlinear crystals of the solid solutions GaSe1-xSx (x ≤ 0.4) by the vertical Bridgman method. The increase in hardness from 8 kg/mm 2 for x = 0 to ~20 kg/mm 2 for x = 0.4 as a result of the presence of sul- fur in the GaSe crystals allowed

One new topological classification of the phase-matching direction loci for sum/difference frequency generation in biaxial acentric crystals is presented. Based on nine fundamental axial wave constant mismatches, 12 locus indices are used to distingu
