| Abstract: | Dual-frequency lasers play an important role in many fields such as interferometry and optical sensing, etc. Progresses of dual-frequency laser techniques in recent years are reviewed, including the birefringent dual-frequency He-Ne and Nd∶YAG lasers and the two-axial-mode semiconductor laser. Operating principles of different kinds of lasers are briefly described. The advantages and disadvantages of the dual-frequency lasers are analyzed, mainly about the frequency-difference and its stability as well as its tuning characteristics. The developing trends of dual-frequency laser technologies are pointed out. |
