OMTech has released their latest entry-level MOPA fiber laser, the MOPA Compact 20. This 20-watt fiber laser has all the impressive metal and plastic engraving abilities of fiber lasers, while adding the fine-tune adjustments with the MOPA features. I put the MOPA Compact 20 through all my tests in this full review.
