Violet 405nm (blu-ray) laser diode closeup #3

Again, close-up of a diode from an HD-DVD player. This time, the metal casing surrounding the diode chip has been carefully removed with a dremel tool (OK, well as carefully as I could!). Now you can see the small laser semiconductor chip sitting on top of the base with the small gold wires attached. This is powered up with ~30mA of power, which is still very bright on the camera, but relatively dim to the naked eye. It is interesting to see the whole chip light up, though :)

I don't get it. Why does the whole room get completely dark after a little tiny light comes on in a perfectly well lit room! Something doesn't smell right!

@uttershock because CCDs are very sensitive to that wavelength and the camera is automatically adjusting exposure time due to it detecting a strong light presence, even if it does not look bright to our eyes.

Read the description, he said he used a dremel to cut the can off.

thats an open can diode right i thought they only came in red??? is that a 6x 8x

[AZURA888]

What price has these laser and what are the mW?.

[howboutdat1227]

omfg thats awesome

Awesome,

one of my 803T diodes had a broken window and when i tried to remove the end of the can to get it out i ended up destroying it :(

Nice vid.
