20mm Osram PLTB450B 1.6W 445nm 450nm Blue Laser Diode In Copper W/Leads

Description

Listing is for a single 5.6mm Osram PLTB450B 1.6W 450nm laser diode mounted in a l
arge 20mm x 30mm copper module
with leads attached..
The 20mm copper module upgrade provides great
thermal capacity and
conductivity
for moving the heat away from the diode to your heatsink giving a very 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 Three Element(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.

Osram 1.6W PLTB450B 450nm Laser Diode
Save yourself the headache of pressing and soldering. Just add glass lens, install module in a heatsink and power with a 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.

Osram 1.6W PLTB450B 450nm Laser Diode
Datasheet
Here is a test of the new PLTB450B 1.6W 450nm diode from Osram. This diode in comparison to the M140 diode offers a better beam divergence and gets pretty close in power about 300mW on average less efficient based on the results of the diodes I have tested. Tested 5 of these so far and they all seem to average about 2W @ 1.8A with a G-2 where the M140 averages around 2.3W @ 1.8A. There is one drawback there is more dye reflection/splash than the M140 with a single element lens. Also this diode has three bond wires compared to the four bond wires found on the M140.
This is the second revision of this diode and like it's 1.4W predecessor and as noted above it still only has three bond wires but this version has added an esd protection circuit.
