hi i am new to this laser thing trying to learn and figuring out about watt and mw of laser that can be use on different type of material so if any advice on them please help me
IDK, I have always thought OPT Laser's prices were a bit high. At $500+ for 6 watt laser heads and $1000+ for double that one can find these at far less expensive prices. But, I'm a cheapskate and hate to overpay for anything.
