Thanks you for your complete reply ! I abandon idea of charger. It was to see if my diode working. Another question: I connected the driver "1.25A SL-D1 survivallaser" with 1 "UltraFire 3.7V 3000mAh 18650" batteries and the light intensity of the LD "445nm diode 1W" is very low, lower than my...

reverse polarity can damages the driver circuit ? Do I need a test load to be on ? Thanks.

Thank you for your response. Another question share: does the driver 1.25A SL-D1 of survivallaser supports Invertion polarity? because I accidentally installed the batteries with the polarity reversed and pushed the on/off button for a few seconds.

Hello, I wanted to know if a portable charger could light my diode laser in complete safety. Is a DDM sufficient to check the output current of charger to see if it is constant and does not exceed 1.2Amax and 5Vmax of my LD (Obviously I will take a charger whose current suits me). My diode...

Bonjour, merci car c'est le premier laser que je construis en France (et je parle un peu anglais :D). Pourriez-vous m'expliquer plus precisemment à quoi sert un Test-load et comment le monter à mon driver afin qu'il delivre une intensité maximale?

I plug a 1 ohm resistance and 6diode will be compatible with my laser diode?

My main question is: With a diode and a 1.2Amax 1-1.4W driver? how to properly set up the driver for the LED operates at its maximum?

Thank you.Test-load are resistors grouping is that it? It reduces the actual output current of the diode. I do not understand, because when we go to connect the LED driver, it would be the intensity of the driver who shall succeed to the diode and not the intensity with the Test-load. Sorry if...

I wanted to ask if I could directly connect the DMM on terminals + LD and LD-driver without using the Test-load. y-he has a difference with or without the test-load?

Thank you for your response, I can not directly measure the intensity out without using a test-load? What is a driver adjustment screw (see link)?

Hello, I own a diode laser 445-450nm (blue) 1W-1.4W, NICHIA NDB7412T, http://img.alibaba.com/img/pb/953/238/672/672238953_683.jpg the maximum intensity is 1.2Amax and 5.5Vmax. So I have not taken the driver 1.25A of Survivallasers and bought it 3.7-4.2VDC 1w 1.4w 2w Blue 445nm 450nm Laser Diode...
