We report on the experimental observation of coherence enhancement of noise-induced intermittency in a semiconductor laser subject to optical injection from another laser at the boundary of the frequency-locking regime. The intermittent switches between locked and unlocked states occur more regularly at a certain value of the injecting laser pump current. A shape of probability distribution of the experimental inter-spike-interval fluctuations is used to quantitatively characterize the intermittent behavior.
我们报告了在频率锁定区域边界处,受另一激光器光注入的半导体激光器中,噪声诱导间歇性相干增强的实验观测结果。在注入激光器泵浦电流的某个特定值时,锁定态与非锁定态之间的间歇性切换会更有规律地发生。利用实验中脉冲间隔波动的概率分布形状来定量表征间歇性行为。
