IR Filter

[whaleofatime]

I am new to the laser world and I have been learning a lot off of this forum. I currently do not own a laser, but I am interested. I am wondering what effect does an IR filter have on a laser? Does it make a laser somewhat safer? I do understand the dangers of lasers and that a filter should not make you relax your safety awareness.

Thanks ahead of time for answering!

Green lasers use a frequency doubling crystal which converts the 1064nm (nanometer) wavelength to 532 (halves the wave-length)

In that process, the IR (1064nm) is left over along with the green and an IR filter removes the extra IR without affecting the greens performance. It is also safer but you should be using safety goggles anyway

You will need to to a lot more reading on DPSS Lasers and
how they produce Laser light using an Infra Red (IR) Laser Diode.
Then you will see why IR Filters are important...

The information is all over the Forum....

Enjoy your stay...:yh:

@ LaZeRz...

In the case of 523nm (green) Lasers the goggles would need to block
the 532nm + 808nm + 1064nm...
The cheaper Red tinted goggles do not block the IR...

Thanks for the replies. I have been looking at jayrob's kits specifically

http://laserpointerforums.com/f64/fs-diy-green-kit-host-heatsink-easy-assembly-22520.html

and also maybe O-like 100 mW module. Is it possible to add a filter to this kit? If so, where could I find a good quality filter to add?

MarioMaster sells some for $6.95 that you can add to that green

You can also ask Jayrob to add it for you.

Jayrob is an awesome guy, you won't be disappointed!

By the way LaZeRz how do you sell 15 dollar Itunes vouchers for 20 dollars?

Sorry for the noob questions but would these glasses work with this set up?

Does Mario Master have an online store? If so, could you post a link?

Im selling a 20 dollar voucher that I have for 15 dollars Im not that crazy!

Those glasses are pieces of crap, get some of the laser shades that Mario Master sells, I have a pair and they block most of my greenie out

BTW, use the edit button instead of triple posting please
