Quarter (λ/4) waveplate – a thin-film compensator. If the angle between the electric field vector of the linearly polarized incident beam and the retarder principal plane of the quarter-waveplate is 45°, the emergent beam is circularly polarized. When a quarter-waveplate is double-passed, such as by mirror reflection, it acts as a half-waveplate and rotates the plane of polarization to a certain angle. Quarter-waveplates are used to create circular from linear polarization or vice versa, as well as for ellipsometry, optical pumping, suppressing unwanted reflection and optical isolation.
Zero-order waveplates are generally preferred because they are least sensitive to variations in wavelength, angle of incidence and temperature.
Standard waveplates are based on air-spaced construction that allows their use for high-power applications. The damage threshold is more than 20 J/cm² for 10 ns pulses @ 1064 nm.
