Abstract
We present, in a first part, the complete elaboration process of AgGaS2 to obtain 4×4×15 mm3 slabs and the first results on ZnGeP2. A two zone oven was designed for the chemical synthesis and the vertical Bridgman method was chosen for the growth. These slabs were tested on optical benches to produce mid-IR laser emissions from near IR sources: results on Difference Frequency Generation are presented in a second part.
