本文报导了内腔He-Ne激光器的一种特殊噪声,它是由空间磁场(主要是地磁)引起的。根据Zeeman激光理论和激光介质的色散特性,解释了这种噪声产生的机制和变化规律。最后给出了消除此类噪声的方法。

We theoretically investigate the delay-dependent attosecond transient absorption spectra in the helium atom dressed by an infrared laser pulse in the wavelength range of 800–2400 nm. By numerically solving the three-dimensional time-dependent Schr dinger

We demonstrate that the filamentation process is strongly influenced by the polarization state of the driver laser. When the laser polarization changes from linear to circular, the critical power for the self-focusing of a Ti:Sapphire laser (800 nm, 40 fs

基于全量子理论,分别研究了几种重要的光场作用下,从原子玻色-爱因斯坦凝聚(BEC)体耦合输出的原子激光的量子相干特性。结果表明,粒子数态光场诱导的原子激光总是反聚束的,相干态光场诱导的原子激光是任意阶相干的,而压缩相干态光场诱导的原子激光总是聚束的。表明用光场诱导产生的原子激光具有与初始光场完全相同的量子相干性质。
A novel assembly control algorithm named burst-size feedback adaptive assembly period (BFAAP) is proposed. The major difference between BFAAP and other similar adaptive assembly algorithms is that the control curve of BFAAP is dynamically adjusted accordi
