I made this series of photos of an IR laser diode of 1W (9mm diode), from various angles, so you
can see their chip from every angle, the layers that compose it, and the connecting wires.
And also I hope this photos serve to show a somewhat different manner (and not only seen them in drawings),
the different layers that make up the chip, in this case of an IR laser diode.
I will say that these photos are not of very good quality, because I do not have a good material to perform it,
but I hope you like them anyway.
Update 02 of May: Added 2 new photos of other infrared laser diode.
For those who want, HERE you have the Link to my other thread with an 405nm laser diode.
Update may 23: Here you have the link to my new thread of an 650nm laser diode.
In these first 2 photos you can see the 4 wires of connection between the chip and the connection pin.
In these 3 photos below, we see very well the active area of the chip.
Also, in this photo below you can see that the chip is somewhat puffed on the right.
Here you can appreciate the different layers that make up the chip.
The following 2 photos belong to a laser diode of the same features but with a small defect in
the active zone, of the left. Added on May 2
In this photo that comes now, of the right side, we see the bad cut in the rear, but you will
see better in other photos, and also that the chip is somewhat puffed up near the back.
In these next few pictures taken from above, you can see perfectly how bad this chip have
been cut, perhaps cutting this with a knife, haha.
Also you can appreciate the 4 wires that connect to the chip.
