摘要

Stability of optical beats in a chaotically oscillating laser is compared to that of a free-running continuous-wave laser using a highly efficient plasmonic photomixer (Anttena). The high stability of optical beats in chaotically oscillating lasers is verified. Near to the laser threshold level, this stability of optical beats is maintained.
