This research project has demonstrated for the first time the analysis of noise properties in a 65mW, 405nm violet laser diode and also stabilized its frequency fluctuations as low as hyper coherent level. We measured the longitudinal mode behavior in some operation conditions, including the ambient temperature and optical feedback amount and so on. With some optical feedback amounts usually seen in typical optical pick-up systems, we have confirmed that the average relative intensity noise (RIN) value measures up to about-125dB/Hz, while the external cavity length dependences of the RIN show maximal and minimal spikes repeatedly at certain points where the external cavity length coincides with integral multiples of the effective internal cavity length of our sample LD. Under such circumstances, we have achieved the suppression of the optical feedback noise to about-132dB/Hz by selecting the polarization of the feedback light. Moreover, we have proved the measured 65mW, 405nm violet laser diode sample tends to oscillate in multiple modes, so that we should carry out the single longitudinal mode operation by controlling the ambient temperature about 15℃. Thus, we have finally attained the frequency stabilization of the violet laser diode using a reference Fabry-Perrot cavity based on the Pound-Drever-Hall method. As a result, we have achieved for the first time the frequency stability of 3.46x 10^<-11> of the minimum square root of Allan variance in a 400nm type violet laser diode.

本研究项目首次展示了65mW、405nm紫光激光二极管的噪声特性分析，并将其频率波动稳定到超相干水平。我们测量了在环境温度、光反馈量等条件下的纵向模态行为。对于典型光学拾取系统中常见的一些光反馈量，我们已经证实，平均相对强度噪声（RIN）值可达约- 125db /Hz，而RIN的外腔长度依赖性在某些点反复显示最大和最小峰值，其中外腔长度与我们的样品LD的有效内腔长度的整数倍相一致。在这种情况下，通过选择反馈光的偏振，我们实现了对光反馈噪声的抑制到- 132db /Hz左右。此外，我们已经证明了测量的65mW， 405nm的紫色激光二极管样品有多模式振荡的倾向，因此我们应该通过控制环境温度15℃左右来进行单纵模操作。因此，我们最终实现了基于庞德-德雷弗-霍尔方法的参考法布里-珀罗腔的紫色激光二极管的频率稳定。因此，我们首次在400nm型紫色激光二极管中实现了3.46x 10^<-11>的最小Allan方差平方根的频率稳定性。
