Thank you very much for you comments. @paul1598419. Yes, I think ZnSe is the proper choice, but I have asked the website edmundoptics.com. They also suggest me this one but they are not sure their beamsplitters can be used with 40W power. How do you think about that? @Alaskan: I also found...

I'm looking for a beamspliiter for infrared laser (10.63μm) with max power of 20W/60W but it seem to be hard. Please help me if you can!

Hi all, @Singlemode: my background is combustion, this is the very first time I deal with laser experiment, especially, infrared laser. So I want to ask for sure 100% even I know about the question. @Encap: I have and he gave me very nice advice. I sketch out 2 method I think they are suitable...

I see. I am figuring out this method. And I see the beam splitter that split the single beam into 2 beams with around 90 degree direction of each other. You mentioned the mirror is for the purpose to get 2 parallel beams, didn't you?

Thank you for your suggestion. I will look into this method, but I have a quick inquire that is this combination can orient multiple laser beams paralleling within an area of 50mm tube and is this combination fine with 60W laser? Thank you.

Hi all, I found some method: - What if I use a diffraction grating to divide a laser beam to multiple beams. But whether the diffraction grating is comparable to the 20W or 60W laser beam. - Another method is to use rotating mirrors coupled with synchronized pulses of the laser to split the...

Thank you your question. We use the gas as mixture for combustion in the tube, so CO2 laser is not absorbed by burned gas, but unburnt gas does. So the flame is exposed by the laser beam only, from that we can investigate the effect of laser beam on flame. I am looking for your reply and...

Thank you very much your response. I am so sorry for this late response, I have busied for conducting experiment. When you look in to the diagram I posted, I have 2 laser generator, one can project maximum 20W and another 60W of single laser beam. The purpose of the set up in the diagram is I...

Thank you very much @Encap and all of you sending me a welcome reply :thanks::thanks:. I'll be back soon with my project.:))

To @Encap I will. would it be ok if I ask you why do you know him? Thank you.

Hi all, I am Tery, I come from Japan, now I am doing some experiments related to laser. Actually, the laser I used is not a pointer, but this is a very actively forum, so I would like to ask your help. I am doing an experiment that projecting a laser beam to a flame which propagating in a...

Thank you very much for your reply @hakzaw1 Here is some spec of the pointer. - 30VDC Input power - Current Rating: 12A - 2.5mm beam diameter - 7.0mR beam divergence - 10.57-10.63µm wavelength - Linear (horizontal) polarization - Air cooling - 15.2" x 4.6" x 5.8" overall dimensions - 20W of...

Dear all, I am a newbie and need your help. I am doing an experiment that projecting a laser beam to a flame which propagating in a tube. I am using device SYNRAD Firestar v20. It can only project a laser beam (beam diameter 2.5mm), but now I want to use a multiple parallel laser beam...
