Low Frequency Laser Debye-Sears Ultrasonic Measurements
Abstract
The frequency range accessible to the laser Debye Sears technique has been extended downward to 7 MHz. Modifications include a 1 MHz piezoelectric transducer, a 5 mW HeNe probe laser, and an extended optical path. The precision is experimentally characterized using the complexation of NaCl and 18-Crown-6 in H2O. The accessibility of lower frequencies permits the detection of a previously unobserved second relaxation.
