Abstract A new multipass cell design is proposed for use with high energy, pulsed lasers and for application to spontaneous Raman scattering diagnostics. Using a Nd: YAG laser pulse of 8 ns, 500 mJ at 1.06 μm, the frequency-doubled 60 mJ pulse is trapped in the multipass cell for 550 ns until it decays to 10% of its initial energy. This gives a resultant gain of 42 over the single pass case and corresponds to a multipass cell efficiency of 97.7% per pass.
