| Abstract: | The knife-edge and harmonic technique in the Scanning Laser Acoustic Microscope is studied in this paper. The operating frequency of the SLAM can be increased from 100MHz to 300MHz by using the harmonic technique. The acoustic images of some samples are obtained on our SLAM at 300MHz. |
