The wait is finally over. No more deep blues with a hint of violet. M462 a true blue laser diode. 

Listing is for a single 2W M462 462nm blue laser diode mounted in a 12mm x 30mm copper module with leads and a three element glass lens. 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.



Save yourself the headache of pressing and soldering. Just add host, heatsink and driver. The three element glass lens will give the lowest divergence of any lens available but has some splash and the 405-G-2 gives about 30% more power and has a cleaner output. I also have a combo with the G-2 instead of the three element. See my other listings.;)

A laser diode is a current-driven device which is should not to be driven by a voltage source. Otherwise electrical 
overstress may occur to the laser diodes as the operation voltage varies from device to device and additionally depends on the case temperature. Special care has to be taken, when switching the electrical power on and off, as transient currents beyond the maximum ratings can occur damaging the laser diode. To operate laser diodes correctly , a proper electrical driving mechanism has to be employed. A proper laser diode driver must be used to act as an accurate constant current source with good transient protection and very low noise. 
Max suggested current 1.8A



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.

Laser Driver - It Can Be Done!



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.;)



2W M462 462nm Laser Diode




Spot size. Now this the best I could do at the moment. I will try to get a picture more aligned later but it is a pain. The spot/line on the M462 is just a little smaller than the M140 and less splash from dye reflection.







Now for the power test with G-2 glass lens. No animals were harmed in the making of this test but two poor diodes were mortally wounded.:gun:






!!!Not Suggested to proceed past this point. 1.8A Max Suggested!!!

!!!Zombified!!!:cryyy:

Zombie running @ 800mA still does 550mW but if you try to increase it decreases in power....

Here is one of my favorite hosts. The Sirius 1-C





 

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