This is our new 3.8W laser that is in our 3.8W laser kits.  It can run at MFG specified 2.5amps at over 3.8W of power!  You can increase your cutting depth and decrease your engraving time by 2X!

This is sold either as a separate component or in an upgrade for existing customers who bought the 2.8W kit with the 2.5amp driver board.  We recommend using a fan upgrade with this laser.

Options:
Just Laser: Includes the laser in heatsink with lens and cable.

Product Description

Laser Overview

This laser is our newest compliment to our laser kits and can run at 2.5amps continuosly to produce over 3.8W of optical power!  This is compared to our 2.8W kit, which at the factory setting only produces 2W of optical power.  You will be able to cut and engrave at almost twice the speed!

The laser is mounted in an aluminum heat sink and has a 3′ cable with a molex mini fit connector on the end.  Lens included is the High Efficiency AR coated lens.  We recommend using a fan upgrade with this laser.

The Upgrade version includes a larger power adapter to support driving the laser and fan at full maximum power.
*Upgrade version compatible with 2.5amp laser drivers sold after April 2015.  Contact us if you have a driver before this date and want to upgrade.
