Links to what you got?

Current setting (mA)?

Type of batteries?

What is it mounted in?

Peace,
dave

It is set to 50 mA with a 9v battery and I have the driver set up on a breadboard. This is what I got here

How did you measure the 50mA setting?

Did you try it with another, new battery?

Default Re: 405 nm Diode dull?

Yes Itried a new battery. I measured the mA on the circuit with a voltage tester. It might be something in the circuit but it was working fine a few minutes before.

Default Re: 405 nm Diode dull?

Does it still draw 50mA? What is the voltage over the laser diode?

Place your DMM in series with the battery and measure the current.

It has most probably turned into an LED, from ESD while changing battery.

Anyways, there's a few things that could have caused this... ESD, if you touched the diode pins without grounding yourself first, maybe you disconnected the diode momentarily when the driver was turned on, charging its capacitor to unsafe voltages, then when you hooked the diode back up it discharged into the diode, perhaps you shorted the resistor or potentiometer, sending the current up to 1500mA for a second, could be a reflection went back into the die causing catastrophic optical damage, or maybe it was just bad juju, and your diode is cursed.
