What is the Verdet constant of glass?

The Verdet constants were found to be 70.1 rad/(T·m) at 193 nm, which is the shortest observed wavelength for silica glass. SQ glass has excellent structural properties; thus, it is suitable as a DUV Faraday rotator for high-average-power optical isolators.

How is Verdet constant measured?

the magnetic field with an associated linear fit. Thus by multiplying the slope by the inverse of the path length l = 3.8cm yields the Verdet Constant. A relative uncertainty of 9.6% was obtained thus making the uncertainty in V = 0.40 · 10−7cm−1G−1. This value can be compared to a theoretical value by evaluating Eq.

How does the Faraday effect work?

The Faraday effect causes a polarization rotation which is proportional to the projection of the magnetic field along the direction of the light propagation. The Faraday effect is caused by left and right circularly polarized waves propagating at slightly different speeds, a property known as circular birefringence.

What is Faraday rotation experiment?

In Physics and Optics, the polarization of light is studied through ”Faraday Rotation Effect” using optical materials like glass, crystals, chemicals etc. Its analogue in radio waves is transmission of polarized wave in ferrites materials.

What is the Verdet constant for sf-59 glass?

The Verdet constant is wavelength dependent and for SF-59 glass is advertised to be 23 rad/m·T for 650 nm light. Thus, by applying 1000 gauss (0.1T) to the 0.10 m long rod, we expect a rotation of 0.23 radians, or approximately 13 degrees.

How is the Verdet constant used in optoelectronics?

The Verdet constant is responsible for the rotation of light in the Faraday effect as well as the magneto-optical Kerr effect. Hence, this material is extensively investigated for potential applications in optoelectronics. In order to define the coherent nature of the response, several experiments were performed (Figure 6).

How is the Verdet constant of a material measured?

The objective of this work was to measure the Verdet constant for different materials. The Verdet constant is measured by using the Faraday Effect which is a magneto-optical phenomenon; mean it describes the rotation of the plane of polarization of light with in a medium when it is placed in an external magnetic field.

What is the Verdet constant at 17°?

At 17° the light appears magenta (green light has been removed), and at 30° it appears yellow (blue light has been removed). These angles suggest the Verdet constant is 23, 30, and 52 rad/m·T for yellow, green, and blue light, respectively.
