Dual Wavelength Waveplates: function, construction and purpose.
What is the main function of dual wavelength waveplate?
Dual wavelength waveplates are optical components designed to manipulate the polarization state of light at two distinct wavelengths.
How Dual Wavelength Waveplates are produced and constructed?
Dual wavelength waveplate production and configuration is similar to low order waveplate. It is relatively thick (when comparing to true zero order) waveplate with specific retardation value plus (integer) number. By carefully designing the thickness of waveplate it is possible to align the phase shifts, so that waveplate has specific retardation values for two (or more wavelengths).

Dual Wavelength Waveplates for Ti:Sapphre, Yb:YAG, Nd:YAG and other lasers
Ti:Sapphire Dual Wavelength Waveplate
Dual Wavelength Waveplate designed to act as a half-wave (λ/2) plate at 800 nm and a quarter-wave (λ/4) plate at 400 nm can rotate the polarization of light at 800 nm while converting linearly polarized light into circularly polarized light (or vice versa) at 400 nm.
Yb:YAG Dual Wavelength Waveplate
Dual wavelength waveplate designed to operate as a half-wave (λ/2) plate at 1030 nm and as a quarter-wave (λ/4) plate at 515 nm achieves dual-function polarization control by introducing a π phase shift for light at 1030 nm and a π/2 phase shift for light at 515 nm. Such a waveplate is valuable in laser processing and microscopy, where the 1030 nm wavelength might be used for imaging, and its second harmonic at 515 nm is employed simultaneously for fluorescence excitation or other nonlinear optical processes.
Nd:YAG Dual Wavelength Waveplate
A dual wavelength waveplate designed to operate as a full-wave λ plate at 1064 nm and a half-wave λ /2 plate at 532 nm construction allows for the maintenance of the polarization state at 1064 nm while rotating the polarization direction of light at 532 nm by 90 degrees.
