Simultaneous intermodulated optogalvanic spectroscopy and laser induced fluorescence in an erbium hollow cathode lamp

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…Bueno et al 145 compared intermodulated LIF and intermodulated optogalvanic spectroscopy using the same experimental set-up. They used a homemade Er–Ar HCL, which is a well-stablished source used in isotope shift studies.…”
