Approach to Polarization Gating with Wave Plates
Explore another technique for polarization gating using multiple order full wave plates and zero order wave plates. Learn about the manipulation of electric fields through group delays and phase differences to achieve elliptical polarization. Separate components before introducing the full wave plate for effective polarization control.

Another polarization gate Other than the polarization gate using a multiple order wave plate plus a zero order wave plate. Another version will be a multiple order full wave plate plus a zero order wave plate. The electric field is first incident on a multiple full wave plate with its polarization axis at 45o with respect to the fast axis of the wave plate. The wave plate introduces a group delay of 6.2 fs between its e and o components Fast axis slow axis ^j This is a linear polarized pulse with time dependent polarization angle w.r.t axis (i.e. different portion of the pulse in time are polarized at different angle ).
The I and j components travel at a different group delay 3.1 ns 3.1 ns
You have to separate the components before introducing the full wave plate
Linear-circular-linear Field linearly polarized after the multiple order waveplate
A zero order wave plate is placed at an angle with respect to the full wave plate. Project the electric field onto the F.A. and S.A (x' and y') ) of the zero-order wave plate. After the wave plate, the electric field becomes: This is a elliptical polarized pulse with its major and minor axis on x' and y'. Its ellipticity is: With the ellipticity is:
