Subject: Can em radiation interact with high energy sound waves?

The question asks if photons and phonons can interact to produce a summation of 
energy enough to trigger quantum level changes in substances such as 
semiconductors. If it is known that this is possible, the different speeds of 
transmission of em and sound energy could be used in various applications. In 
particular, I am interested to know if monochromatic radiation could interact 
with a broadband pulse of sonic radiation to stimulate broadband absorbsion of 
radiation in any known substance.
