Hey everyone.
Just doing some laser thinking, and I have come to the conclusion that we should be seeing expensive, yet viable, handhelds in the form of these wavelengths:
689nm - 1319nm + 1444nm
664nm - 1319nm + 1338nm
659.5nm - 1319nm + 1319nm
632nm - 1122nm + 1444nm
612.5nm - 1064nm + 1444nm
610nm - 1122nm + 1338nm
606nm - 1122nm + 1319nm
571.5nm - 946nm + 1444nm
561nm - 1123nm + 1123nm (easy? Just normal frequency doubling...)
554nm - 946nm + 1338nm
551nm - 946nm + 1319nm
546nm - 1064nm + 1122nm
513nm - 946nm + 1122nm
500nm - 946nm + 1064nm
The reason why I say we should be able to get handhelds in these is that three of the wavelengths that aren't easy to produce, 946nm (becomes a "quasi-three level gain medium", which means its harder to pump), 1319nm, which is not a hugely powerful line of emission, and 1342nm, which is one of the weaker lines of emission of Nd:YAG, are found in three of the four common DPSS laser handhelds (473nm, 589nm, and 593.5nm).
The point of the matter is, why is it so "easy" (relatively speaking, considering these other wavelengths) to make handhelds out of 473nm, 589nm, and 593.5nm (!) while we cannot make one that is at, say, 546nm (two of the stronger lines of Nd:YAG - 1064nm and 1123nm).
And you know what? Those are just the five or so strongest lasing lines of Nd:YAG. There are tons more - if you are curious, just check out CNIs website under DPSS modules, and look at the IR section - most of those are Nd:YAG lines that are just directly outputting that wavelength.
Anyway, who wouldn't want a 500nm laser in a handheld, or a 554nm (or a 556nm, like rhd and arythna have ) in a handheld? What about a 606nm? That's pretty damn orange. Maybe 612.5nm?
Point is, there is a lot we could be having now... so why don't we have them yet?
