电弧涂层螺旋电极无声共振放电二氧化碳激光器
Arc Sprayed Helical Electrodes Resonant Silent Discharge CO2Laser
摘要
研制成功了共振逆变器激励无声放电快速轴流二氧化碳激光器,其电极是以电弧涂层法制作,覆盖于石英放电管的外壁。电极几何形状采用了平行和螺旋等方式,实验证明螺旋电极比平行电极的放电更为均匀,输出也较高。此激光器以CO2:N2:He=1:17:2的混合气比及5 kPa的氧压操作,输出225 W功率时能量转换效率8%。
Abstract
A type of fan axial flow CO2 laser based upon resonant silent discharge has beendeveloped successfully.Its electrodes were arc sprayed on the surface of fused silicadischarge tubes,and.the discharge was sustained by a resonant inverter tuned at about 100kHz. The sprayed electrodes proved excellent adhesion, and the belieal ones offered verygood discharge uniformity. When operated at 5 kPa gas pressured and CO2:N2:He=1:17:2 mixing ratio, the output of this laser was 225 W with 8% wall plug efficiency. The very high and low contents of N2 and He in the mixed gas made this laser different from others.
