      Good question. Pink is not a pure colour (it’s not made of a single wavelength, like each of the colours of the rainbow). Although violet is close to pink, if you want to get real pink you have to mix red and white. White can be made from combining, for example red green and blue (this is how your computer monitor produces white). So if you had a laser giving off some green, some blue and lots of red, it would look pink.

      So yes, this is possible.
