This is achieved by using a unique multi beam technology, demonstrated in figure 2, which reduces the power density, minimizes the thermal load, and reduces the kerf width in the wafer.

这是采用独特的多光束技术实现的，图2显示了其工作原理，降低了功率密度，减小了热负载，缩小了刻线宽度。

When the initial power equals the critical power a stabile spatial soliton is obtained and generally the beam width takes periodical contraction or diffraction.

当初始功率等于临界功率时，可以得到一个稳定的空间孤子，而一般情形下，束宽则作周期的压缩或展宽变化。

Nereus, on the other hand, uses rechargeable lithium-ion batteries, similar to those used in laptop computers, for power and a single hairs-width fibre optic cables - borrowed from Torpedoes - for control and telemetry.

Treviso demonstrated from the off that they intended to play with pace and width but from the first scrum Leicester began to butcher the home pack and their forward power laid the ground work for the victory.
