The Pulsar produces bursts of ultrasonic energy, adjustable up to 1000watts acoustic power.  The price is $6,500.00. 

The  Pulsar  uses  a  two-inch  diameter  (piston source)  ultrasonic  transducer in a four-inch diameter aluminum package.  The  frequency  of  operation  is  typically  660 kilohertz, which yields an acoustic beam about nine degrees wide. This beam actually increases in intensity for the first 19 inches of travel, before beginning to expand at the nine-degree rate. 

Continuously adjustable controls are: POWER from less than 1/10 watt to 1,000 watts(1.35 horsepower);   PULSE   DURATION   from   50   milliseconds   to   one   second;  PULSE REPETITION   RATE   from  1/10  second  to  three  seconds;  FREQUENCY  from  640 kilohertz to 690 kilohertz.  To  provide  the 1,000  watts acoustic output, the electrical power supplied to the transducer is typically 1250 watts. 

The  ultrasonic  beam  is  clearly  visible when viewed through aquarium glass. This allows the beam  to  be  studied,  for standing waves, or for reflection and refraction. There probably no better way to study nonlinear wave propagation. 

We  stand  ready  to  modify  the  Pulsar  for  use as a sonar source, either a linear source or parametric source.
