okay.. noob question here. how much power does direct driven 445nm with a 18650 battery puts out? will a lm317 driver set to a specific miliamp outshine a 18650 battery direct driven 445nm diode?

is it possible to laser water?(water as a lasing medium)

i know sunglasses are useless against lasers.. i have an od3 laser goggles that works.. but i am wondering what happens when you shine it through a welding googles. anyone tried that before?

So... Which brand of batteries do you prefer to go with you lasers/flashlights/whatever electronics? try to give a reason why you choose that particular brand, and also a reason for why you wont use any particular brand Me?- i choose tesco for its price and energizer for reliability. if you...

which is more visible red at 650nm or blu ray diode, assuming both driving at 120 mw?

how much mw is needed to burn paper ?(not make holes, but IGNITE) before you ask what colour... i want to know both Black or White.

what happens to a laser diode when overdriven without a heat sink? will it go off instantly or will it become slightly dimmer over time?

how much is shipping to UK?

what is the fastest and safest way to remove a diode from a dvd heat sink?

i always wondered.... how much output is sunlight on a sunny afternoon(in mw terms) and how does 3x magnified sunlight fare with lasers.., i know it is not collaminated.. but it sure is strong at max focus. anybody ever tried measuring the output?

is there any topics regarding which burners to buy?(or not to buy) i have heard Lite-on is nothing but bad news for DIY burning lasers. why? anyone post a link/ photo what/why not to buy?

what should be the output voltage of a dvd burner diode at 350 ma if i dont want to fry it?(using ddl driver and 5 aa battery)

how much output is an infrared producing if it glows as bright as a 3mw red laser pointer? i tried running 320ma at 6 volt through laser inthe pioneer dvd burner drive

i killed a diode from this drive while testing. it is a light scribe burner with long open can anyone has further info on diode inthis drive?(ie output, mA, voltage?

so now i have what appears to be a crude DDL driver(lm317, 10ohm resistor, 47uf cap, 100ohm pot,1n4001 diode), i have a few questions 1: can i use 4x AA battery to power the dvd burner diode with the Driver? 2: what kind of output will i be getting from 4x AA batteries with pot at maximum? 3...

anyone has the any info of lasers on this Panasonic SW-9588-C drive? i took apart one before i was interested in lasers, but i remember seeing 2 laser diode inside.

hi. i jst bought my 1st aixiz module, and i am having difficulty seperating the top and middle part. :'( any suggestions?
