噴嘴的直徑決定了從噴嘴中噴出的氣體流量和氣流形狀。材料越厚，氣體噴流的直徑也要越大，相應地，噴嘴口的直徑也要增大。

氣體純度和氣壓

氧氣和氮氣經常用作切割氣體。氣體的純度和氣壓影響切割效果。   采用氧氣火焰切割時，氣體純度需達到 99.95 %。鋼板越厚，采用的氣體氣壓越低。   采用氮氣熔化切割時，氣體純度需要達到 99.995 %（理想情況是 99.999 %），熔化切割厚鋼板時需要更高的氣壓。

技術參數表

在激光切割早期，使用者通過試運轉自行決定加工參數的設置?，F在，成熟的加工參數被存儲在切割系統的控制裝置中。對于每一種材料類型和厚度，都有對應的數據。技術參數表使得即使不熟悉這種技術的人也能順利操作激光切割設備。

激光切割質量評價因素

有許多判定激光切割邊緣質量的標準。像毛刺形式、凹陷、紋路等標準可以用肉眼判定；垂直度、粗糙度和切口寬度等則需要采用儀器來測量。材料沉積，腐蝕，熱影響區域和變形也是衡量激光切割質量的重要因素。
