Diode laser spectrometer for high-resolution spectroscopy in the visible range

摘要

A high-resolution diode laser spectrometer op- erating at 657nm is described. To achieve a narrow linewidth and a high power a master-slave laser system is employed. The master laser is an extended cavity diode laser whose linewidth is reduced to less than 100Hz by the FM sideband technique. The slave laser is an AR-coated Diode laser and characteristics of injection locking are Experimentally studied.
