Have 2 lasers - one isa 75W CO2 with a proprietary RE3 controller/SW from Full Spectrum, the latest is a 5W UV Galvo from Nanjing (customized) and the third is a $300 Amazon unit (“5W” diode). (like I said, I have 2 lasers, lol). Bear in mind, wattage among laser types is NOT an apples to apples comparison. waveLENGH matters.
