Abstract
WE recently described1 an optical etching technique for producing small optical gratings in which a metallic film is used as a Q-switch for a ruby laser system. We have been able to produce line spacings as small as 180 nm using frequency doubled ruby laser radiation in the optical arrangement of Fig. 1; this corresponds to band 13 on Nobert's finest ruled test plate2. With further doubling of the laser light, spacings of order 90 nm should be obtainable.
