Abstract

Implementation of a new high energy, IR laser source for secondary neutral mass spectrometry, is presented. It consists of an 800 nm, 40 fs, 10 mJ, 1 kHz laser pumping an optical parametric amplifier generating 1.2-2.6 μm tunable pulses. The wavelength and intensity dependence of photoionized sputtered indium clusters and gas-phase histamine are presented, exhibiting less nonadiabatic multielectron dynamics (decreased fragmentation) at longer wavelength. Future prospects for secondary neutral bioimaging experiments are explored with a model system consisting of a 400 mesh grid, vapor deposited with adenine, and fixed over indium foil.
