Recent proposals for scientific experiments utilizing the SLAC Linac Coherent Light Source (LCLS) have underscored the need for compressing or truncating its nominal $\tilde{\hspace{0.4em}}$ 200 fs pulse length down to $\tilde{\hspace{0.4em}}$50 fs or less. Of the various optical techniques considered for shortening the pulse, the focus of a series of recent studies has been on methods based on the interaction of a longitudinally chirped LCLS pulse with a specially designed multilayer [1]. Here we present results of detailed studies of both pulse slicing and compression schemes capable of attaining durations of less than $\tilde{\hspace{0.4em}}$10 fs.
