532 nm filters: I have been building a number of 532 nm lasers. There have been questions about filters to remove the IR component and just wanted to pass a little information along to those who are interested. I use IR filters in all my builds and if you are looking for some there are a quantity or 5 IR filters 9.5 mm square and 1.1mm thick on eBay item # 110887324982 for $15.98. These filters have a high transmission for 532 nm >97.5% and a low transmission of IR at 808 nm and 1064 nm <2%. Just wanted to pass that along to anyone interested in building these DPSSLs.

I am having a problem with the X-Buck 1.8 amp driver by Lazeer and would like to get a schematic of the driver or at least a pin out diagram of the IC. Intermittently my power output goes into the mud and the input voltage is fine @ 7.4 volts dc. This happens every so often and once this driver blew out my LD.

Turns out the problem was the laser diode. I didn't know at the time that these diodes could be intermittent.
