GaAlAs 二极管激光器 842 nm 输出的二次谐波是在谐振外环腔中的 KNbO(3) 晶体中生成的。通过反向传播基波的反馈，二极管激光器在光学上稳定到环形腔，该基波在谐振器中被弱激发。我们在 421 nm 处产生了 6.7 mW 的可调谐窄带辐射，并使用该光对铷的窄跃迁进行饱和光谱分析。
The second harmonic of the 842-nm output of a GaAlAs diode laser is generated in a KNbO(3) crystal in a resonant, external ring cavity. The diode laser is optically stabilized to the ring cavity through feedback from the counterpropagating fundamental wave, which is weakly excited in the resonator. We have produced 6.7 mW of tunable, narrowband radiation at 421 nm and have used that light to perform saturation spectroscopy on narrow transitions in rubidium.
