  11. I suppose a laser beam direction could be controlled
  12. by using a piezoelectric crystal setting up standing
  13. acoustic waves in an elasto-optical glass rod.
  14. However, I know nothing about this stuff yet, and I am
  15. very curious. Can anyone recommend a good book? Are
  16. the parts expensive?
