Default optics to combine focus lasers for cutter/etcher

I've been having this idea for a while, but at this time I am really stuck, most lasers I've seen don't really have a really small focus , and the higher power ones are really expensive. I was thinking there are laser diodes out there in the 300 to 500 mW range and well there are two problems they mostly make a line not a dot, and two power is kinda weak.

was thinking 300 mW red laser should be enough to etch paint if I can focus the thing to a really tiny dot, this would be at a fixed distance that would never change.
#2 a lens or two to reconvert the line into a more focused dot would be cool. When I was a kid we experimented with different types of lenses, for example you could use a magnifying glass to focus the sun into a smaller dot and if it hit a different type of lens the then focused dot could be converted into a stronger beam that was parallel and could travel for a while (theoretically indefinitely if there is no obstruction, and then you could use another lens to focus that beam down even further.

we did this stuff for physics classes. I don't remember the lenses used but I do know there were concave and convex lenses some with one flat side that we used in those experiments any body here experiment in doing something like this with a laser? i.e using a 1 axis lens to convert the line into a dot and the use another lens to make it go from focusing back to parallel and then maybe use another lens later?
does anyone even make lenses that would be suitable for this that could be gotten at a decent price to experiment or does anyone remember sources of parts that could be slaughtered?

Default Re: optics to combine focus lasers for cutter/etcher

I have built a CNC engraving machine that is used to custom etch chips. It is capable of some sick precision. I cant give you info on the CNC mechanics but i can tell you what you want to know. The lens form a laser printer is really good! I used a DVD RW diode and printers optics. It's darn good. Here is a photo.

can you show pictures of the optics setup?
I built reprap's so cnc 2 axis should be easy enough
you know what dvd-rw laser you used? or will anyone pretty much do?

Default Re: optics to combine focus lasers for cutter/etcher

A 405nm diode like the S06J or BDR-109 will
work a little better, but the 660nm diodes
are much cheaper right now. The 660nm
diode to use would be the ML101U29-25.
Personally, I would go with the 405nm just
because it is hotter and will mark on more
surfaces. For the lens, all you need is a
single plano convex element to focus. You
would need something like the 405-G-2 since
a laser printer lens would be coated for IR
if it is even coated at all.

Default Re: optics to combine focus lasers for cutter/etcher

Depends on what would you like to engrave.
I used 660nm an 808nm because i had no other choice. If i had a choice...445nm or 405nm. They are cheap and have a lot of power.
If you want to experiment,you can use any DVD/CD burner. There are some open cans diodes out there,they seem to be the most powerful. But that's a luck game.
Diodes in burners go up to 200mW. The optics in printers are probably not coated for anything,so its not that great. If you want a efficient,powerful setup,go with The Lighting Stalkers advice.

I have a module like that sitting here on
the table. How did you get that lens off?
They are VERY stubborn.

The lens is secured by a plastic black ring(its on the picture). U just unscrewed it with a screwdriver. The plastic is very weak so it tends to break if you force it. The metal holder part came of easy, it was secured via some kind of glue.

Default Re: optics to combine focus lasers for cutter/etcher

I managed to remove the lens. The process
involved a hammer and punch. It is a
very close slip fit. Even though the
hardened glue wasn't adhering, it was
enough to jam up the tiny gap between the
module and lens. The lens itself looks
like a twin element like an achromat or
possibly just a GRIN lens. It's hard to
tell if there is an actual seam or if my
eyes were playing tricks on me. The focal
length looks like about 15mm. It looks
like these LaserJet 4P printers may have
some IR coated optics.

Hammer fixes everything
I don't know about coating,but honestly,its not that important if used only for experiments.
Buying adequate lenses and modules is always the way to go.
