Are there cheap lasers other then red, green, violet and blue?

Searching for colors not in common, that are not really expensive.
do they exist at all?
for example:
we already have dark blue(445nm) what about light blue?

Yellow is to expensive for sure.
Orange maby?
White?
Gray?
Olive green?
more?

Lets see....

Orange: that would be either 593.5, which is less than 589 but still isn't cheap IIRC

Orange could also be had as the wavelength 635, which is a lot closer to red but is apparently much more orange than 660. These are cheap for ~7mW, and you can find them on Hightechdealz.com for like 3.99 IIRC. Higher powers are likely to run a scarier pricetag, but I haven't looked into it.

White: white is expensive, and to make it you need 3 different diodes precisely aligned. One of the easiest kits for it is the White Fusion kit, a search should give you a FS thread. I don't think it is a viable option for handheld though.

Olive Green: they are coming out with different wavelengths of green, and I have heard rumours of a lower wavelength green possibly around 520nm, so possible, but it would like be quite expensive as that would be in the developemental stages atm.

Light blue is 473nm or 488nm, but 473 is very expensive and so is 488, although I am not sure I have heard of any handheld 488s, handheld 473s are very much available.

Those are the ones I know of, hope that helps! :beer:

Some company is working on green laserdiode. Maybe in near by future 520nm color got cheaper.
 
Wow isn't that enough cheap lasers :crackup:
Of course there are different colors than them but they arn't cheap :cryyy:
 
Olive green would be closer to the 561 in my sig (sort of a yellower green), whereas 520 would be a blue-green, not more olive.

If we see direct green diodes, they'll likely be around ~520.

You may want to look at 545 Green HeNe. It's not -that- hard to get, and its definitely visually a much different color than your usual 532 green.
 
BorgQueen I think the WhiteFusion build is the way to get cheaper exotic colors via 1 Red and Blue diode and a Green module combining.
 
There are fairly low cost IR lasers, I know not a visual color, and how can you beat the CNI GB offer of a 589nm 1 mW pen that is $250 + PP and shipping? :) -Glenn
 
get a mixed gas (argon/krypton) laser, plenty of colorfull lines to choose from :D
 
Black lasers are real cheap- no batteries needed either. No eyeware necessary.
