Low powered 445nm diode

[yobresal]

I have a Casio A140 diode pressed in module. The diode works but for some reason it low efficiency. I have performed tests on this diode and it gives out 1/5 the output that normal A140 diodes put out. After viewing the spot unfocused I assume that this is due incomplete coating of the die. There are non emission lines in between normal lines. Instead of a normal rectangular spot it is a rectangular spot with horizontal strips of no light. This diode will be a nice one for someone who wants to build a low powered 445nm. I am not one of those people.
@ 1.1 AMP diode puts out 200mW.

If anyone is interested price is $15 shipped.

What current does it begin lasing?
What is the optical power at the point it begins lasing?
Is it just as hot at 1.1A as the regular 445nm diodes?

I might take it if it doesn't turn into a super heat generator with that input. I still might take it even if it does...

if the problem is the coating, probably it will heat just alike a 445 common casio heats at 1.1amp. Maybe a little more, because of the reflectivity of the laser, absorving light on himself.

I have not tested the lasing threshold of this laser though I assume it to be the same amperage as a normal A140 diode.

I'll take it if it's still available
