1.5-2W 445 nm Blue Laser Diode In Module W/Leads

Description

Listing is for a single 1.5W-2W M140 445nm blue laser diode mounted in a 12mm x 30mm copper module with leads attached. The copper module upgrade provides a huge
improvement
in thermal
conductivity
over the standard brass module for moving the heat away from the diode to your heatsink which gives a much more stable output from the diode.
Please Note this module comes with an acrylic lens in it to keep dust out. It can not handle the power this unit can put out. It will keep contaminates out of the module until you are ready to put yours glass lens in. Replace with your glass lens of choice before powering the module. The best options are the Aixiz 405/445 Glass Lens or the 405 G-1 Lens. If you need a lens with the unit I do offer this unit in a combo with a three element or with the G-2. See my other listings.
Save yourself the headache of pressing and soldering. Just add host, heatsink, glass lens and proper laser driver.
Don't attempt to connect the diode directly to a fixed voltage source like a battery.
The diode requires a proper laser driver to operate.
I also have options for this diode in modules with the driver installed
If your application is for CNC Engraving check out my CNC page with lots of links to tutorials and recommend parts, software and modulating drivers suitable for CNC.

There are many other proper laser drivers but be careful a lot of sellers here are offering LED drivers as a laser driver which can damage or cause shortened life to the diode.
LED drivers are not laser drivers
. LED's are tough as nails but laser diodes are much more sensitive and need extra features like soft start, overshoot protection and a very low noise output that are standard on laser drivers but not included on LED drivers. I have seen a a few tutorials for building a "cheap laser" with
this LED driver
but it is a bad idea as I see it causing a lot of diode deaths. If you do use a LED driver you do so at your own risk.

This is 700mA it was just flashing between 6/7 at the time the picture was taken and I did not notice it.
