In this work we are investigating the interface between two bonded optical crystals used for laser generation. Sapphire and Nd:YAG crystals were bonded by use of room-temperature surface activated bondig technology. The bonded interface was measured with TE microscope and EDX was used to invesitgate material composition of amorphouse layer. With the help of annealing the amorphous layer transformed into crystaline.
