Dual Wavelength Waveplate
Dual wavelength waveplate is a special type of multiple waveplate that provides a specific retardance at two different wavelengths, it’s particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength. It is widely used to improve conversion efficiency in solid double frequency laser device.
