Listing is for a single 5.6mm Osram PLTB450B 1.6W 450nm laser diode mounted in a large 20mm x 30mm copper module with leads and a high pass G-2 glass lens. 
The 20mm copper module upgrade provides exceptional thermal capacity and conductivity for moving the heat away from the diode to your heatsink giving a very stable output from the diode.



Check out this thread for details.




Save yourself the headache of pressing and soldering. Just add host, heatsink 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 offer a fixed X-Drive laser driver set to 1.8A for this diode. You can find it here.
I also have options for this diode in modules with the driver installed see these
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.
