At the same time under the direction of Figure lobe half-power beam width of the main requirements to determine their unit number and unit spacing.
同时根据方向图主瓣半功率波束宽度要求确定其单元数和单元间距。
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。
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。
The formulas of mode conversion are derived and effects of optical beam power, initial beam width radius and inverse of the radius of curvature of the wave front on the mode conversion are analysed.
导出模式变换公式，分析了光束功率、光束初始的束宽半径和波前曲率半径的倒数对模式变换的影响。
The results show that the rational combination of welding parameters such as the laser power density, the welding speed, the pulse frequency and pulse width influence the quality of the weld beam.
焊接过程中合适的保护气体及其送气方式也是十分必要的。大量试验表明，激光功率密度、焊接速度、脉冲宽度和脉冲频率四个参数的合理组合是实现不锈钢薄板焊接的关键因素。
