Available in PDF, EPUB and Kindle. Book excerpt: Efforts were continued on a program to design and fabricate optical filters at three different laser wavelengths: the 6328 A helium-neon line, the 1.06 micron neodymium line, and the 3.5 micron neon-Xenon line. Filter Type I was designated to be helium-neon laser filter, centered at 6328 A with a half-power bandwidth of less than 2 A and peak transmission greater than 40%. (Author).
