Abstract
A comparison is made between the use of the quarterwaveplate and Fresnel rhomb over the 10-μm emission region of the CO2 laser. From 9.24 to 10.74 μm a quarterwaveplate for the 10.6-μm CO2 spectra line can give rise to a total phase shift of 97–176° for the respective lines. A Fresnel rhomb exhibits virtually no phase variation from the desired 90° phase shift over this region. Both devices exhibit phase shifts for light not normally incident on them.
