you mean that is we can't make wavelength from other wavelengths,so how to add wavelengths

yes , you are right , but when we insert 2 laser beam each with own color to planner optical diffraction grating ,with a certain angle , they appear at the destination port as a new laser beam with a new color (new wavelength) , qustion how to calculate this wavelength? are you understanding me?

hello , everybody, i need help please i want to combining two laser beam (coherent lazer) , but i don,t know how to calculate the new one i have the value of the two wavelengths (.6328 micro ) and (.5145 micro ) but how to get the new one ? can i take the average of them ?
