Abstract

A high-resolution 0.4-m monochromator is described for use in wavelength diagnosis of tunable pulsed and cw laser sources in the 3000–10000-Å region. The f/20 design uses an echelle grating in an over-and-under Ebert configuration with a scanned photodiode array to provide a real-time multichannel display of spectral output. Absolute wavelength may be determined to 0.1 Å with the monochromator, and a Fabry-Perot interferometer attachment extends linewidth measurement capability to 0.01 Å or better. Spectra are displayed on a storage oscilloscope, and calculation of laser parameters is explained. The instrument measures 70 cm long × 15 cm wide × 20 cm high.
