AI 中文摘要
飞秒激光脉冲具有巨大的潜力，但仍面临一些性能和稳定性问题。在这里，我们发现了一种新的非线性光学效应，即频率梳诱导的受激布里渊散射共振，这种效应只能由一种新型孤子——自适应孤子——激发。自适应孤子具有独特的自适应下啁啾特性，这打破了正常色散激光器中脉冲能量的面积定理限制；其光谱轮廓自调节特性提供了高脉冲对比度，并打破了放大器中增益窄化限制；同时它不受色散辐射的影响，而色散辐射会削弱和扭曲当前超短激光脉冲在传输介质中的表现。更有趣的是，它们在正常色散波导中具有自适应传输增益，这有可能使它们在长正常色散波导中实现无损耗传输，从而用于无中继孤子通信。我们成功构建了一台被动调频锁模光纤激光器，并产生了极其稳定的自适应孤子。尽管该激光器没有负色散元件，但输出的孤子被测量为下啁啾，这使它们能够在正常色散波导中保持孤子特性，非常适合波导传输的超快应用。凭借高一致性、高脉冲对比度和高能量能力的优势，自适应孤子在微加工、激光手术、量子计算和光谱学等领域表现出色。
英文摘要
Femtosecond laser pulses have incredible potential but still face some performance and stability issues. Here we discover a new nonlinear optical effect, frequency-comb-induced stimulated Brillouin scattering resonance, which can only be excited by a new type of soliton, adaptive solitons. Adaptive solitons possess the unique properties of adaptive down-chirp which breaks area theorem limitation on pulse energy in normal dispersion lasers, spectral profile self-regulation which provides high pulse contrast and breaks gain narrowing limitation in amplifiers, and freedom from dispersive radiation that weakens and deforms current ultrashort laser pulses in transmission media. More intriguingly, they have an adaptive transmission gain in normal dispersion waveguides which has the potential to enable them to be lossless in long normal dispersion waveguides for repeaterless soliton communication. A passive frequency-modulation mode-locked fiber laser was successfully built and generated incredibly stable adaptive solitons. Even though the laser had no negative dispersion elements, the output solitons were measured as down-chirped which enables them to keep soliton properties in normal dispersion waveguides, perfect for ultrafast applications with waveguide delivery. With the advantages of high consistency, high pulse contrast, and high energy capability; adaptive solitons are excellent for fields including micromachining, laser surgery, quantum computing, and spectroscopy.
