We report a dual-frequency injection-locked continuous-wave near-infrared laser. The entire system consists of a Ti:sapphire ring laser as a power oscillator, two independent diode lasers employed as seed lasers, and a master cavity providing a frequency reference. Stable dual-frequency injection-locked oscillation is achieved with a maximum output power of 2.8 W. We show its single longitudinal/transverse mode characteristics and practical power stability, as fundamental performance features of this laser system. We also demonstrate arbitrary selectivity of the two frequencies and flexible control of their relative powers by simply manipulating the seed lasers, as advanced features.
我们报道了一种双频注入锁定连续波近红外激光器。整个系统由一个作为功率振荡器的钛宝石环形激光器、两个用作种子激光器的独立二极管激光器以及一个提供频率参考的主腔组成。实现了稳定的双频注入锁定振荡，最大输出功率为2.8W。我们展示了其单纵模/横模特性和实际功率稳定性，作为该激光系统的基本性能特征。我们还展示了通过简单地操控种子激光器实现两个频率的任意选择性以及对它们相对功率的灵活控制，作为其先进特性。
