Abstract
The variation of the acousto-optic figure of merit M in (GaAlN) single crystalline solid solutions with x, temperature and pressure are investigated. It is revealed that an increase of x up to 2.5% leads to an increase of the coefficient M and for higher x we observed a decrease of M. An increase of M with a decrease of temperature below 35 K was also found. The acousto-optical coefficient M reaches its maximal value at 4.2 K. Negligible influence of hydrostatic pressure on the acousto-optical properties of was found. In our opinion this reflects the high stability of the mentioned crystalline solid solutions.
