基于调节转移技术稳定激光二极管的频率

阐述了利用调节及转换技术稳定激光二极管发射器的频率 ,这种发射器可以发射纳米波长的激光。通过分析两个相互独立的激光器系统中存在的振动信号 ,知道该振动信号已揭示了在 0 .0 9秒的时间内有 10 - 1 1 秒的时间频率是相对稳定的 ,并且在 1秒的时间内似乎可以得到 10 - 1 2 的最低干扰频率。为避免产生共振 ,充分吸收铯元素的D2 线作为频率参考及非线性光谱研究

Study of frequency stabilization of diode laser using the regulator transfer method

Absolute frequency stabilization of diode lasers of wavelength nm grade are reported using the modulation transfer method.The analysis of the beat signal between two independent laser systems has showed a relative frequency stability of 10 -11 for an integration time of 0.09s,and a frequency noise floor in the order of 10 -12 for an integration time of 1s seems attainable.Saturated absorption D 2 lines of cesium atoms have been adopted as a frequency reference and the nonlinear spectroscopy.
