Who are you? I haven't been trolled in some time. You must have been here before under a different user name. I have built many dozens of lasers of all wavelengths and powers and have been a member in good standing here for well over five years. You signed up today. I would not be surprised to find you banned from here by the end of the day.

Miya what is the runtime duration and the cool down duration? At 620mA I can run my diode for over 10 minutes. I have been doing this for over 7 months now. It is a great wood burner and insect zapper.

I have one violet laser GH04W10A2GC diode 1amp . I can run my diode for max 10 sec because pen build
It is alive for 5 months !!!. so i want 1.4Amp set next time :D

i don't want BDR209 anymore.. However, quality is liked.
How much Max have you set the current for the Sharp diode?
And can you tell me how long the diode been alive?
i need advice before set 1.4Amp current for GH04w10A2GC

I ran th sharp diode at 1100mA for about 30-60seconds ( over 3 days) before it led'd on me. I used a 20mm DTR module in a survival s3 host.

what fun is a thang if you can only use it for 10 seconds? If you want real output with long runtimes, then I suggest a NUBM44 or at the least a 5 Watt 450 Diode.

i love violet color. so 1.4Amp is very danger. Thank you for your advice.
but It's worth a challenge.

I would say your best bet is to place the diode in a solid piec of copper, like the one used in a pentium processor heat sink with a fan and a TEC . I have had a 14W 808 stack that worked very stable using this method . I think the violet mm diode could be run pretty high with stability. I was considering this approach, but alas-The tiredness got me.

Finally Lasertack has sent me 8 of their new mirror prisms designed especially for 390-440nm region.
So I can continue with KE of 4 of these LDs (the picture was in post 55 of this thread).
I am planning to put this set on ice box to keep diodes at rt.
