The efficiency of an ion-etched laminar holographic grating was measured at near-normal incidence in the 14.5{endash}16.0-nm wavelength range. The grating had an electron-beam-evaporated Mo/Si multilayer coating matched to the grating groove depth. The efficiency peaked at 16.3{percent} in the first inside order at 15.12nm and 15.0{percent} in the first outside order at 14.94nm. These are believed to be the highest efficiencies obtained to date from a multilayer-coated laminar grating at near-normal incidence in the EUV ({lambda}{lt}30.0 nm). Zero and even orders were almost completely suppressed. The grating groove efficiency in the first order approached the theoretical limit of 40.5{percent}. {copyright} {ital 1997} {ital Optical Society of America}
