My problem is unrelated to lasers. I already have the laser picked out. The issue has to do with glass. That's why I posted my question in the optics forum hoping someone here might know. There's a difference between unwillingness and inability.

Ok yea I was hoping someone who actually has used quartz before would answer but thanks for the help and I appreciate the effort I will have to do it the hard way hahaha

Why different wavelength, the quote said quartz is great for ultraviolet wavelength light. The only thing between 445nm and UV light is violet light. Blue is the closest we can get for such a low price in the power we need. Do you have any idea how much power would be lost through say an inch...

Thanks josh. This is an answer I was looking for. The box with be heated to that temperature after the laser ignites whats inside, its only use is to get the process going. As for the 5000F temp, the glass at 3000F should do the trick because it may not be directly exposed to this type of...

wow I didn't come here to have an adult (assuming you are one... hard to tell) insult my intelligence. I'm a 21 year old engineering student so I'm sure I have a lack of understanding of basic physics. And I don't recall asking for glass that is a "100% efficient window" so I'd appreciate it...

Why is trust an issue when I'm asking a simple question about glass? I would like to know if there is a high temperature resistant glass that can allow a laser to pass through it without attenuation. I came to a forum to get a quick and efficient answer if anybody knows, not to build a...

Basically we have decided on lasers for a specific reason suited to our purpose. If we could use a transformer I'm sure my team would have thought of that already. My question was about glass so if you can't answer it don't reply please.

Well I'm glad you can ascertain that from the "nothing" I told you. Don't worry I'm a mechanical engineer not an electrical engineer, that's why we work on a team. Thanks for the help

I can't say much its proprietary lol Creating an arc would require a lot of voltage which my team and I don't have the luxury of as we won't have access to it after testing. Sorry I wish I could go into further detail, I realize that makes getting help harder for me.

Hahahah yea I need it to ignite something in a sealed chamber through the glass. The glass must let the laser pass through and must be able to withstand 5000F in temp actually not 1000. The laser is not in the chamber.

Is there a type of glass out there (say quartz maybe) that is strong, can withstand temperatures above 1000 degrees Fahrenheit and can allow a 445nm 1.4W blue laser to pass through it unaffected?
