Changing red diode for a Blu-ray diode

[JimmyV]

Ok, I am set to recieve my FXLAB Pulse 2 laser (80mW red) today and I am thinking that when I am done messing with it in a few weeks, i will be wanting to modify its operation.

I was considering puting in one of those 150mW Blu-ray diodes that are available on ebay from Korea (or Blu-rry as the chaps at my local Richer Sounds call it) and run it straigh off the wires from the old diode.

Could I simply whip out the old 80mW red diode and drop in the new Blu-ray one? I know that it will take a bit of time to get the optics aligned, but I do like the pretty colour

Is this a bad idea?

I know that the diode I was looking at comes with a driver board. Is that so that the power going into the diode is electrically stable? (forgive my lack of understanding here, I'm not so electically in the know :-) But I can usually work things out when I want to.

Thanks,
James

Hey, i think that the blu-ray diodes prefer a higher voltage, mine is running at 5.2v at the diode, i just looked now. as for how much current to put through it... havent measured that!

if you look here http://www.laserpointerforums.com/fo...num=1217284580 Drlava's 405 roundup graph is quite useful as to how hard you want to drive the blu ray higher current shortens the lifetime, but gives you brighter output (but im sure you already know this )

Thanks, thats some great info !

I think that it will take quite a bit of reading to get the voltage right, as a straight swap might either pull too much power from the FXLAB's board, or be underpowered. This is where I begin thinking that I should have studied harder at electronics at school !

Link to 150mw blueray please?

it's probably just a PHR-803T diode - most people only run these at 110mW but that is pretty much the best ratio for power to life for that diode. Keep in mind PHR-803Ts are only rated at around 60mW.

chance of getting a 150mw BR -803t about 0%. Some people say they get 110mw. I have never gotten one over about 80 to 90mw.

I got 110mW out of one.

I got 110mW out of one.

as I said..."Some people say they get 110mw" you are the one but have you gotten 150mw? How many have you done and what has been your average? My average is about 80 to 90 mw

I set mine at 120mW... I had a 200mW PHR that last about a week or so. I know of a couple people running theirs at 160mW and they've lasted forever. It almost seems like the 'original' PHR-803T sleds that were pulled out of devices worked a bit better than the new ones we get from retailers in china. But who knows... Sometimes I get ones that last forever at 120mW, other times they die almost instantly at 120mW. 80-100mW is a pretty safe level
