A laser ablation mass spectrometer for planetary exploration

Using a commercially available diode pumped Nd:YAG microchip laser (/spl lambda/ = 1064 nm, 12 /spl mu/J, 0.6 ns, /spl sim/7 kHz repetition rate) positioned outside the test vacuum chamber and focused to a 20 /spl mu/m spot on the target using a 24 mm doublet lens, mass spectra from several metals,...

Description
Summary:Using a commercially available diode pumped Nd:YAG microchip laser (/spl lambda/ = 1064 nm, 12 /spl mu/J, 0.6 ns, /spl sim/7 kHz repetition rate) positioned outside the test vacuum chamber and focused to a 20 /spl mu/m spot on the target using a 24 mm doublet lens, mass spectra from several metals, mineral glasses, mineral standards and meteorites are obtained.
