The standard DVD burner diode puts out 100mw CW, and 240mw pulsed. Check out the experiments and mods section to see more info on the dvd burner diodes...as far a regular handheld "storebought" unit goes.....Glowtorch on ebay (see my earlier review as well) has a great deal on the 200mw reds....it takes 2 CR 123 lithium batts, and pumps out PLENTY of burning power ! Focusable optics, too Love it ! PM me to get one faster....I bought two, and only relalllly need one !
That depends.....what did you pay for the pulsar ? The Glowtorch ones are running right at $265 now - another good source is SikLasers on Ebay - they sell modules, not the hand held units, but they are HIGH quality - about $175 shipped ($60.00 shipping to the US) and they ship FAST, too. I have both a 100mw and a 200mw red module from them - the 100mw comes with an external driver circuit - whereas the 200mw has the driver built into the module housing - so you get the module about the same size around as a nickel, and about 2 inches long, with wires leads coming out of hte back...including one for TTL modulation - useful for laser shows
