When an intense laser is focused into a gas jet, very high-order harmonics can be produced. The harmonics are emitted approximately with the Same efficiency up to orders as high as 143 and to energies as high as 1 XO eV (6 nm). They have the same characteristics as the generating laser: they are collimated, intense, coherent and of short pulse duration. Thus, these phenomena are interesting not only from a basic point-of-view as a probe of the response of an atom to a strong laser field, but also, from a more applied point-of-view, as an interesting soft X-ray source, with specific properties. The radiation can be used in traditional applications in atomic, molecular and solid-state physics, such as lifetime measurements. More “exotic” applications, such as the production of attosecond (subfemtosecond) light pulses, have also been proposed. Both aspects, the understdndillg of the physics of harmonic generation, as well as the applications of this new XUV radiation source will be reviewed. 09:OO JFAP (Invited) Recent Progress of Nonlinear ShortPulee Tunable W V and XUV Generation
当强激光聚焦到气体射流中时，可以产生非常高次的谐波。谐波的发射效率大致相同，最高可达143阶，能量高达1 XO eV (6 nm)。它们具有与产生激光相同的特性:准直、强、相干和短脉冲持续时间。因此，这些现象不仅从作为原子对强激光场响应的探针的基本观点来看是有趣的，而且从更实用的观点来看，作为具有特定性质的有趣的软x射线源。该辐射可用于原子、分子和固态物理的传统应用，例如寿命测量。更“奇特”的应用，如生产阿秒(亚飞秒)光脉冲，也被提出。从两个方面综述了对谐波产生的物理认识，以及这种新型XUV辐射源的应用。[09] JFAP(特邀)非线性短脉冲可调谐微波及XUV发电的最新进展

Snb-10O-fs klla-repetitioii-rate ainpliliers combine the benefits of high peak powers with the possibility of using sensitive signal-averaging tecliniques. The technique of chirped pulsc aniplification (CPA) led to significarit progress i n the amplification of femtosecond pulses. llecent advances resulted i n the generation of optical pulses of 30 Is duration a t the TW level a t a repetition rate of 10 I I z . ' . ~ A t klIz repetition rates pJ-energy 304s (Ref. 131) and 0.9-mJ 214s pulses4 have recently been reported. Uoth results have been achieved by using complex and lossy grating-based pulse stretching systems. In this contribution we report for what we believe is the first time on the generation of sub-mJ-energy femtosecond pulses without using a pulse stretcher. We have developed a compact eight-pass Ti:S amplifer, which is seeded with -10 Is, 100nm-bandwidth pulses (@ 800nm) from a mirror-dispersion-controlled Ti:S oscillator. The system can be safely operated without an additional stretcher because the pulse broadening introduced by the pulse slicing and isolation components is sufficient to prevent nonlinear effects and damage in the amplifier crystal. In contrast with the conventional approach, pulse selection by a Pockels cell is performed only after the full 8O-MHz pulse train passed through the amplifier crystal four times. In this manner, ASE could be dramatically suppressed as compared to previously reported results.' Carefully placed apertures prevent the high-gain amplifier setup from lasing. After amplification the chirped pulses are recompressed in a setup consisting of dispersive mirrors and a low-dispersion FK5 (Schott) prism pair, resulting i n a quartic-phase-limited amplifier system.
Snb-10O-fs倍频放大器结合了高峰值功率的优点和使用敏感信号平均技术的可能性。啁啾脉冲放大技术在飞秒脉冲放大领域取得了重大进展。光子技术的进步导致产生持续时间为30is的光脉冲，达到TW级，重复频率为10i1z。”。最近报道的重复频率有pj -能量304s(参考文献131)和0.9 mj 214s脉冲4。利用复杂的、有损耗的基于光栅的脉冲拉伸系统取得了良好的效果。在这篇贡献中，我们报告了我们认为是第一次在不使用脉冲拉伸器的情况下产生亚mj能量的飞秒脉冲。我们开发了一种紧凑的八通Ti:S放大器，该放大器由镜像色散控制的Ti:S振荡器提供-10 is, 100nm带宽脉冲(@ 800nm)。该系统无需额外的拉伸器即可安全运行，因为脉冲切片和隔离元件引入的脉冲展宽足以防止放大器晶体中的非线性效应和损坏。与传统方法相比，Pockels单元的脉冲选择仅在完整的80 - mhz脉冲序列通过放大器晶体四次后进行。通过这种方式，与之前报道的结果相比，ASE可以显著抑制。”仔细放置的孔可以防止高增益放大器设置产生激光。放大后的啁啾脉冲在由色散镜和低色散FK5(肖特)棱镜对组成的装置中被重新压缩，从而形成一个四分位限相放大器系统。
