Q-switched parameters by ink colour
Read the transcript
Ink colour decides the wavelength, not the other way round. Black and dark blue absorb one thousand and sixty four nanometres. Red responds to five thirty two. Greens and light blues need different wavelengths again, and they are the ones that frustrate people. Get the wavelength wrong and you heat skin instead of pigment. The Level 5 course teaches the pairing, the test patch and the endpoint you are looking for.
