A Study on the Synchronization Characteristics of Thermoacoustic Laser

Sung Seek Park, Seung Jin Oh, Won Gee Chun, Kuan Chen, and Nam Jin Kim
Abstract—Thermoacoustic lasers convert heat from a high temperature heat source into acoustic power while rejecting waste heat to a low temperature sink. Recent research mainly focuses on using thermoacoustic engine arrays. Therefore, this study mainly focuses on coupling two thermoacoustic lasers. The coupling between the two lasers was started at 0o crossing angle, where the openings of the lasers were parallel to each other and separated by a distance of 1 m. The next configuration was to focus the sound waves using two different crossing angles (30o & 90o) between the two lasers, with their opening ends placed very close to each other. As a result, we conclude from all the measurements made for both the 30o and 90o crossing experiments that synchronization between two lasers is possible when their open ends were placed close to each other.

Index Terms—Thermoacoustic laser, convert, crossing angle, synchronization, sound pressure level.
