Claim 19:
20. A method to deflect a laser beam, comprising:
applying the laser beam to an optical element having one or more steps each with a predetermined height and first and second crystals or transducers electrically coupled in parallel on the one or more steps with first and second radio frequency (RF) electrodes positioned on the first and second transducers, wherein
the first RF electrode selects a first deflection response and the second RF electrode selects a second deflection response; impedance matching the electrical input of the transducers to a 50-ohm load; providing an electrical input to deflect the laser at the two or more frequencies; and generating a sound field in the optical element to deflect a laser beam based on two or more frequencies.
