focus lens would usually have AR(anti-reflective) coating on them. Ask your lens manufacturer what's AR rating of your lens.
PS: any material will bounce some of the beam back, even mild steel(especially metals if you are using 1064nm laser).
Thanks Chalked. Unfortunately there's no way to switch on the fly, say pierce then cut. I have to select the mode prior to cutting. Would pulsing mode change the gas consumption?
Hi guys,
I have recently got chinese 500W fiber laser with IPG source. The source has continuous and quasi modes. I only cut in CW mode with good success.
Can anybody explain why would I use QCW(pulsing) mode?
Thanks in advance
