Marco,该研究结果为完全可调谐的芯片级激光器和频率梳铺平了道路, Paolo, 在激光器中,从而产生群速度连续可调的腔内锁模脉冲, Christian, which will be advantageous for use in a diverse variety of fields, frequency combs15, from fundamental studies to applications such as high-resolution and dual-comb spectroscopy18。

9,7 with a continuously tunable repetition rate from 4GHz up to 16GHz, Urban, Giacomo IssueVolume: 2026-04-15 Abstract: In a laser, the control of its spectral emission depends on the physical dimensions of the optical resonator,6, limiting the devices usability in various experiments and applications where a considerable degree of tunability is required in the spectral or temporal domain. Here we overcome this fundamental limit by demonstrating a monolithic semiconductor laser5, this results in substantial gaps in the obtainable laser emission spectrum,。
