Why are there no other laser colors?

What I mean by that is, how come there are no colors that are darker or brighter? For example: 600nm, 500nm, 555nm, 420nm, 460nm and soforth.

Any plans to make magenta laser color?

Lasers give off spectral colors (https://en.wikipedia.org/wiki/Spectral_color), of which there aren't actually that many. These are colors that have specific wavelengths, but human color perception creates other colors from multiple wavelengths that stimulate combinations of red, green, and blue photoreceptors. Really, any spectral colors are pretty much going to be in the red, orange, yellow, green, blue, (indigo), or violet category. Magenta is a non-spectral combination of red and blue or violet, so to get a laser with the color, you'd have to combine beams. 405nm and 660nm combined work out pretty well for what I'd call magenta.

A triple diode RGB laser might be able to produce almost any color you want. Multiline gas lasers can also create non-spectral colors through multiple wavelengths.

There are many if you know where to look. Such as this place. Green laser blue laser red laser UV infrared laser, diode pumped laser, green-yellow violet lasers

There are super continuum lasers that output many spectral colors.https://www.youtube.com/watch?v=I7_E_sOOl9U

Fully adjustable multi colour laser. Produces shades of peach, teal, pink, and most importantly white! The revised version includes a very fine control over the three primary colours (red green blue) when compared to the 1st version which used slide potentiometers to adjust in a single pass. The user now has the ability to fine tune the output colour via 3 rotary, 25 turn pot's. The internal laser head is temperature controlled in order to maintain your favorite colour by stabilizing all three laser's output wavelength. All packed into a simple one handed package, this laser only boasts 115mW (stable), but its not about power, its the beauty of the light : )

Great links Steve! :thanks:
That super continuum laser would be a blast to own, although the cost alone would probably make you see "colors"!
