LOL I though you meant single wavelength like in the OPs "Your favorite wavelength"( singular) list that has Pink Red (660-690nm) and assumed you were making a joke about it.Huh? I never said it was it's own wavelength. What crawled up your rear end? You need to chill
Sure, you probably could cobble together some combination of wavelengths that give the illusion of pink laser with time and money to burn-- like people who create the illusion of other wavelengths with RGB lasers---go for it.
