So, yesterday, I dropped my blue RPL and guess what, the diode no longer powers up. I know for sure because I've already removed the crystal set and the LED indicator lights red and no light at all, even through a camera. A friend of a friend was playing with my dog and ran into me from behind causing me to drop my laser on the concrete, so there's now a noticeable dent on the aluminum on the front of the laser, so warrantee is out of the question. I have experience and the safety equipment required to fix it myself, as it really isn't that hard. The crystal set is bolt-on as it is collimated and set perfectly as stand alone, four screws mount to the heat sink and base of the laser where the C-mount diode easily can be soldered and replaced. My problem is finding the correct diode. n light won't sell to anyone other then OEM suppliers, and there are a few on ebay that look good. I was thinking about this one but I don't want to go overboard either. And So I PMed a few of our LPF sells people, in hopes to find the one that will work best.

Ouch, thats a shame, hope you can get it fixed, also hope this helps :

No problem, I'm sure you will find the right diode, asking jack about it might also help.

Jack needs to update his site, there's actually a couple disputes on this fact here on LPF, but he claims it is the same LD that's used in the greenies. Check 'review' on my sig and you can read where Jack clears it up. I know which LD it is, but they won't sell to me. It's a piece of cake to replace, just finding the right one for the best price is what sucks!

You might be able to work something out with jack and buy a diode or a broken green RPL with the diode still intact. I imagine you could get a mode hopping and underspec RPL-165 for cheap and take the diode out. According to jack the blue and green RPL's use the same diode.
Can you possibly post some pics of the dead diode? I have no idea what these things look like inside and no intentions of taking mine apart.

I wonder how much it would be for an underspec RPL 165 :-? If its cheap enough I could ask jack for one thats got 1.2mRad divergence or something :-?

You would be best off asking jack how much it would be for either the diode or an underspec RPL 165, and if you get the price for the underspec RPL 165, can you tell me please ?

ace is the distric attorney pressing charges for killing the dog and murdering your friend :-X
Man, it really sucks to hear that your laser broke. 
However, many companies will offer repairs, even after the warranty expires, for a price. Try asking Jack if you could send back your laser for repair.
Oh, and you should make your friend's "friend" cover the cost of any repairs.

Hey, I found out it's not the diode! It's the driver! It's not putting out any current! I learned that the entire laser can be unscrewed, like a flash light! I unscrewed the aluminum base, and swapped with my other RPL, and the LD works fine! I even held the crystal set to it and it lased 473! Now I just need to find out what went wrong. There are a couple things I'm concerned about though...
It said "473 - 20" in hand writing on the base on the inside... :-/
And when I unscrewed it there was lots of aluminum shavings all over the circuitry... :-/
Hum.... :-/
