ما هو ليزر UV 355nm - ولماذا يهم التبريد
355nm UV lasers are essential in PCB marking, DNA sequencing, glass etching, and OLED repair, thanks to their high energy density and ultra-fine precision. But did you know? Only 10% of the input power becomes UV light — the other 90% turns into heat. That’s why precision cooling is critical for stable laser operation and …
