Extruding of water power increases the speed of gasscattering, which makes gas fully release, reduce the gas pressure goes beyond the limit and have remarkable effect to safety production.
At relatively high pressure, in addition to electromagnetic field and electron's Coulomb scattering by gas molecules, plasma instability would result in decrease of propagation efficiency.
而较高气压时，束电子除受自身电磁场作用及库仑碰撞散射外，等离子体不稳定性使束流传输效率明显降低。

Combination of stimulated Raman scattering properties of gas and solid laser harmonic technology greatly expands the covering range of the wavelength.
