Abstract

We demonstrate a method of cascading multiple diffractive elements for improving the purity of spectral dispersion. The cross-axis cascade was implemented in a two-stage grating spectrograph, resulting in a hundredfold reduction of stray light and a high dynamic range up to 75dB. The technique can be used for parallel spectral measurements and processing.

Optical spectra in the two-stage cross-axis spectrograph. (a),(b) Spectra measured after Grating1 (a) with only LED light as an input and (b) with both LED and intense green laser light. Green stray light produced by Grating1 is overlapped with the rainbow spectrum. (c),(d) Spectra measured after Grating2 (c) with only the LED input and (d) with both the LED and laser. The stray light lies along the vertical and horizontal lines, easily separable from the spectrum along the oblique axis at about 45°.
