Abstract

It has been shown that any optical device (e.g., prism, grating, Fabry-Perot interferometer, Lummer-Gehrke plate, Michelson echelon) having an angular dispersion of dε/dλ introduces a tilt in the pulse front. An optical device having an angular dispersion can be converted into a monochromator. An expression for the spectral resolution of such a monochromator measured at the 50% level is given. Due to the difference between the phase and group velocity, the pulse front is delayed with respect to the phase front when traversing a lens or lens system. The delay is a parabolic function of the input radius r and is related to the longitudinal chromatic aberration df/dl. A lens with chromatic aberration can be converted into a monochromator by putting a pinhole in the vicinity of the focus. An expression for the spectral resolution of such a monochromator measured at the 50% level is given. A four-prism pulse compressor is shown and discussed.
