摘要

我们开发了一种短外腔（EC），可为具有宽光学增益曲线的量子阱二极管激光器提供单频激光。所提议的外腔的一个特点是使用由两个薄（厚度约为 100 微米）盖板玻璃组成的谐振反射镜作为反射镜。配备了类似短EC的HL8338MG激光器可以在输出功率约为20 mW的情况下，实现100 GHz范围内的连续光学频率调谐和12.3 nm范围内的离散波长调谐。通过在低压射频放电中观测到 829 nm 附近的三条氪吸收线，证实了这种可调谐二极管激光源在气体光谱学中的适用性。

Tunable Diode Laser with a Short Tandem External Cavity

A short external cavity (EC) providing a single frequency lasing of quantum-well diode lasers with broad optical gain profiles has been developed. A feature of the proposed EC is the use of a resonant reflector formed by two thin (with thickness of approximately 100 µm) cover glasses as a return mirror. The HL8338MG laser equipped with a similar short EC made it possible to demonstrate the continuous optical frequency tuning within 100 GHz and discrete wavelength tuning in the 12.3 nm range with an output power of approximately 20 mW. The applicability of such a tunable diode laser source for gas spectroscopy was confirmed by the observation of three krypton absorption lines near 829 nm in a low-pressure radio frequency discharge.
