This ad says these are 1W and are a different part number than the 500-700mw Sharp 520's
Has anyone tested one yet ?
I don't know how hard these can be driven, but I expect this is curtains for the old ndg7475 when these sell new for 40 bucks.

Sharp 5/10pcs 520nm 1000mW Green Laser Diode TO-9 GH05C01B9G | eBay

Protect your yourself from the laser when you operate on it. These tests are sampling examples from a specific lot for reference purpose only.

It would be nice if they could be overdriven to 2W, but even better would be if the single mode 300mw 520's ( GH0523AD2G ) can also be overdriven, but we shall see, some can be and some..... not so much. I have a couple of the single modes ordered, someone should test this multi mode 520nm.

EDIT: The 300mw 520's are also multi mode but likely with a smaller emitter size, the Sharp data sheet reflects the same.

I have the NUGM06 diodes which do well over 2 watts but they are "g-ball" diodes... However, I've finally found a source for the diode caps and will hopefully have those soon.
 
So what is the difference between the GH05C01A9G and this GH05C01B9G other than the price ?

The 1A9G is the old 500-700mw that we push to 1W and this 1B9G looks very similar on the data sheet except 1400ma suggests it's stronger by some amount, although I can't find the 1A2G data at Sharp.

Perhaps the A series were a pre-release/Alpha version or not intended for public sale kind of like the NUBM44's. I've still got a few of the A series remaining but I will certainly be getting the B ones next.
