Hi there!
I just joined this forum as it seems like a very knowledgeable one with professionals who visit regularly.
Basically I have a few questions regarding building a small size laser.
I currently own a 200mw red laser pointer which I obtained through DX for $30. It is about the size of an oversize pen (or a bit larger). Basically I need something a bit smaller. Edit: I realize the batteries (CR2 I think) take up most of the room, but I am not going to worry about that in the 'small size' right now.
The purpose of this laser is to easily cut thin fibrous threads, such as carpet threads.
I have tested the DX laser (100mw) and it did cut the thread, but after some focusing.
I was thinking of using a 300mw laser diode which should serve this purpose.
Also, does anyone know what type of lens I would use if i wanted to turn this (super focused) laser beam into a Flat line, which would be similar to the thickness of a shark knife (or really thin). Edit: I have seen various 'focus line' adapters, but do not know which one would be optimal at this point.
If I did end up figuring out how to 'spread out the beam' into a flat line, would there still be enough power to slice through fibers?
Also, if anyone know where to purchase reliable laser diodes (possibly with heat sync and potted) online (other than ebay and DX or FP), that would be great! How much would I be expected to pay for a good 300-400mw laser?
Thanks,
