电光调制激光器:由理论光谱导出脉冲能量和对比度增强

Electro-optically modulated lasers: pulse energy and contrast enhancement derived from theoretical spectrum

Denis Marion, Jérôme Lhermite

摘要:

本文用解析方法导出了相位调制产生的频率梳输入同步强度调制器时脉冲激光源的复光谱。然后,我们将展示如何这种知识的光谱可能有助于实现前所未有的准确性,在实验光谱校正步骤通常进行了一个光谱处理器。在数值示例中,对于给定的平均功率,峰值功率增加了75%,消光比提高了至少三个数量级。该方法还能够使用Talbot效应对这些通用相干源进行大因子速率倍增,而信号的退化可以忽略不计。

英文摘要:

In this article, we derive analytically the complex optical spectrum of a pulsed laser source obtained when a frequency comb generated by phase modulation is input into a synchronized intensity modulator. We then show how this knowledge of the spectrum may help to achieve unprecedented accuracy during the experimental spectrum correction step usually carried out with an optical spectrum processor. In numerical examples, for a given average power we present up to a 75 % increase in peak power and an enhancement of the extinction ratio by at least three orders of magnitude. This method also enables large-factor rate-multiplications of these versatile coherent sources using the Talbot effect with negligible degradation of the signal.
