advise on what to buy

[ReaperZ]

Hi guys,

just wondering which laser you would reccomend buying,

i currently have a 50mw green laser, its very bright however it doesnt appear to set match-heads on fire, would this be due to not actually being 50mw ? or is a higher spec laser required for this ?

i have up to 100usd to spend, would also look at second hand options if someone is selling something ?

i do prefer green over red - looks a lot cooler i realise red is a lot better for burning (correct ?)

if someone can post some links that would be much appreciated !!!!!!

PS im from New Zealand and i found this site very helpful

Many Thanks

50mW isn't enough to light matches, even if it was overspec. You would need about 100mW to reliably light matches, but lower powers can, if focused properly, light matches. Red is not better for burning, but red is able to reach high powers much easier then green, but if they are equal, green will burn just a tiny bit better, because it has a higher wavelength, which means it has a higher energy density. This is not noticeable, and if the red was just a few mW's more, it would burn better. I also prefer green over red.

Even if you do prefer green over red, you're not going to get much green for $100 so you could get a 200mW red focusable (dilda) for 43.65USD shipped.

many thanks for these links, and also to the others who have offered advise

the chinese girl who sells these lasers has advised me she can do a 90~100mw green for $65usd and she advises it WILL light matches relatively easy, has anyone bought one of these from her and confirm it ?

ive also just been given a dead old laptop which has a dvd writer in it, so ill attempt to make my own red laser just need a pot, lens, battery and solder right ?

will a lens from a cheap $2 5mw red laser work ?, also is there any particular grade wiring i need ?
