So my $1400 XJ-A140 arrived yesterday. Before ripping the guts out I watched some Lord of the Rings using the HDMI port. This only lasted some 5 minutes. Then the dissection procedure began.
The first power-up revealed to true brightness of these diodes. Blinding! The 24 diodes reflected off a white wall catching me off guard. There was an immediated black square in my vision. Thankfully this has disappeared this morning. I rushed for my OD 4 laser goggles.
I've attached some pictures of the laser outside. There was no smoke or fog about. You can see how the yard lights up blue! The other picture shows the beam into the sky. (After checking for no planes first) Using the standard lenses with very short focal points gives an extremely uncollimated beam. Even so, the beam still looks pretty awesome.
After all this I hooked up one diode to a Flexmod driver. Threshold was 170mA. I ran it at 1.2A for around 10 minutes. To my surprise the heatsink was still cool to the touch. My overall optimistic project is to build a multi watt blue laser. I'll let a few of these diodes go for $70 if anyone is interested. I know it is way over the usual asking price but I had to pay quite abit more for the A140 projector here in South Africa. Drop me PM if you wish.
