Efek Magnetooptis Pada Lapisan AgBr Terekspos
Abstract: The non linear optic
characteristic from several transparent medium (film plate and glass) under
influence of external magnetic field and variation of wavelengths, have been identified.
In this experiment, the developed AgBr film is deposited on a hologram. The
magnetic field has been produced by coils which connected to slide regulator
(0-240V). The maximum value of magnetic field is about 182,0 mT. Light sources
used are He-Ne Laser with a wavelength of 633 nm and 1 mW in power, and green
laser pointer with a wavelength of 532 nm and power less than 5 mW. The optical
characteristic measured in this experiment is the rotation of electric field,
of the transmitted laser beam due to applied external magnetic field to the
medium. The experiment result shows that
is dependent linearly on magnetic fields. The Verdet constant is
proportional with wavelength of the light. Measured values for Verdet constant
(V) at 632,8 nm is (0,487300,00070) min/G-cm and at 532 nm is (0,261700,00056)
min/G-cm for glasses material and the values for Verdet constant at 632,8 nm is
(0,328500,00060) min/G-cm and at 532 nm
is (0,156900,00039) min/G-cm for film plate.
