Check out this thread for details.


Here is what you get. A brand new PLTB450B diode.

If this is your first laser build here is a great place to start.


 

Diodes are current hungry and as they heat up their internal resistance is lowered causing them to want to draw more current. Don't attempt to connect the diode directly to a fixed voltage source like a battery. You must use a "constant current" power source like a current limiting driver or variable current power supply with the current limited to no more than 1.8A or you diode will suffer thermal runaway and die. For more info on the reason for a constant current driver see this thread.

Here is the Pinout for the diode


If you are looking for a host here are some of the more popular host/heatsink kits that will work with these diodes and if you want something that is not listed in those links that I show in my tutorials below shoot me a message and I can point you in the right direction for them.;)




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.







Here is the power test done with a G-2 and random cool down periods. @ 2A it started working backwards on output. @ 2.1A it stopped lasing and dimmed but like most the newer diodes it just shut down instead of going LED or open circuit and came back to life when the current was turned back down.







































And there you have it. I will get some more pictures added with raw output and spot size later.

Here is a list of tutorials I have made and experiments that can help give you ideas for your next project.
