Forget about 593.5nm, 589nm, 488nm or even 500nm, all that is common when compared to the rarest wavelength :)

Which wavelength would you guys consider to be the "rarest" laser WL ever made. If possible I would also like an explanation of why it is so rare, I.e is it the price? How hard it is it produce? Dosen't have much use? Etc...

"The rarest of wavelengths is the wavelength not made." - Me pretending to be Confucius.

In my mind though, the rarest has to be 607nm or so. Because it isn't really available. I think Bloompyle or Zraffleticket had a source at one time but the cost ended up being insanely high and I think it dried up by now also. I would do many things for a powerful true orange laser.

^Haha, I can't even imagine the price of a 607nm laser. I have been reading old threads on LPF and it was mentioned somewhere is cost around $3,000-$4,000 yikes :eek:

Man, thought you´re done with such questions ;)

But there is a 365nm diode available, 607 DPSS, 622nm diode and also some others. But you need exceptional good technical understanding / creativity and mostly quite a good amount of money you´re ready to invest. Think nowadays it´s possible to create every wavelength in the visible speectrum.

500nm is not even common compared to wavelengths which aren´t existing yet , but you may know more than me ;)


Edit: Isaac, had a contact about two years ago. The 300mW of nice 607nm DPSS would cost less than 2K knowing the right sources. CNI even agreed to build it into the PGL-III-C or better the Herc back in the days. But no one was able / willing to pay such an amount.

There are (arguably) infinitely many wavelengths that are only possible with a super-continuum laser. All of these are therefore equally rare.

I apologize DJNY for all these questions, just trying to learn about lasers!

About 607. Even though it's a very, very unique wavelength I don't find it really appealing to me, but I know others love it! I find 593.5 is as close to "orange" as I want to get, as least until they drop down in price :)

Look at your 635, now look at your 594. Now the 635. Now the 594. Now put your lasers in a row. See that big gap between yellow and red? How dare there be gaps that huge! And I bet it would be an awesome color!

I don't see 607 dropping below $1000 ever, unless some sort of "ultra HD" projector comes out.

Kvant offered me a module so long as I provided dimensions, and it'd end up >100mW (probably 200) at somewhere between 2500 and 3500.

Needless to say, it never happened.

Oh trust me im sure in many years when they are more reasonably price and possibly made into a pointer(*fingers crossed*) I'll go ahead and buy one haha. I have spent waaaaay too much on lasers since I joined and I really need to save up for my future, im really happy my last purchase for awhile was a yellow which is what I have always wanted :)

There's lots of rare ones we don't see much in the hobby. How do you decide what is rarer? CuVL? HeHg? UV HeCd? HeSe? Raman HeNe? Etc. Of the ones we normally hear about I guess it'd be the 607.

All about supply with 500nm...I'm not sure of any specific uses for it, not to say there aren't any. Heck, you could pester some companies for a 500nm diode I bet- prepare to pay an arm, leg, firstborn child, and your left shoe:

That's a problem because increasing indium concentration in the active layer above 15% makes the semiconductor crystal more prone to defects that impair laser operation. That difficulty stalled the push from blue to the longer (488 nm) wavelengths through 2008. In early 2009, developers finally broke through that barrier to demonstrate GaInN laser diodes emitting at 500 nm. Two different approaches to growing laser structures on GaN substrates succeeded at about the same time, and both are still in the running.

Speaking of 607, has anyone contacted CNI to ask how much it would cost to get some Pr:pAYAC? I want to know, but at the same time I'm sure it will make me cringe...

Not from CNI, but I was quoted $250 from another company long ago.

Didn't DJNY get a 50mW 556nm unit from CNI for some large figure?

I believe it's the only such unit on the entire forum.
