Anyone know a reasonable cost source for structured media for continuum? I need to pump it to make a continuum but I need enough power after the shift to shg to the UV. Right now I have a tisaph 980-800. So I can reach 490-400. But I’d like to get 600-400 but still have enough power for shg...

Anyone have ideas on how to drill a 1mm hole in a first surface mirror? Due to size constrains I need to do this to sample a beam used for illuminating a sample. It’s a reference beam so I. Figured to sample through the back of a turning mirror. I have no other location in the light path to...

Says 5.00 for 575nm. Not lasence. Likely too good to be true but…. https://m.alibaba.com/product/1600236664933/575nm-laser-Diode-modules-574nm-laser.html?__detailProductImg=https%3A%2F%2Fs.alicdn.com%2F%40sc04%2Fkf%2FH6c338b4a5b3d4d03893ff7ebdc7fa874O.jpg_200x200.jpg

Well I sold mine and now I wish I had it. IF anyone one has a 465-475nm diode let me now. It doesn't need to BE 473 just in that color space. Certainly no less than 465 and not longer than 475. Power doesn't matter. 30-100mw is fine but i do want to modulate it and I do not want dpss. It's...

I have access to dry inert boxes at work. I was thinking to decan some ball diodes in various gas and see what happens. I’m thinking nitrogen’s d another in argon. Nitrogen is not inert. What diodes do you want to see and I don’t have a power meter so what do you suggest? I was thinking to...

is there a host that fits the new numb series of diodes or do they have to be decanned. Anyone sell such a decanning device? Also I use to have a nice set of mounting blocks you put the diode in then it the back to mount it. Who sells those anymore?

happy fathers day to all those who are not a father Not everyone is a father BUT EVERYONE IS A FATHER TO SOMEONE OR SOMETHING. Happy caretaker day. M

Thanks to all that think that much of my contribution. I do try to not be dead weight.

Ok so its a dream to think you could double these guys but can you? I mean if I put 6w of 445nm in and get 10mw of 222 or 202 out of it that would be something. Looking for 200-210nm for a nitrate spectrometer and I dont want high voltage or gas discharge. Hoping for solid state as it goes in...

Well I’m pretty well known on the other forum. I’ve been a member here since 2012 and well I’ve not really been active over here. I decided to come by and see the place and find I really like what I see. So hello here I am. My interest is in lumia at the moment and spectroscopy which is how...
