✦ Synopsis

The effect of pressure on the phase (6) of the photoacoustic signal in alexandrite was considered theoretically. It is shown that increase of pressure induces a non-linear increase of S. The possibility of using the normalized phase difference shift of the photoacoustic signal in alexandrite upon pressure as a new method for high-pressure measurement in the diamond anvil cell is discwwd.
