We describe a cryogenic Faraday isolator with a gadolinium gallium garnet (GGG) crystal used for the first time as a magneto-optic element. Simultaneous compensation of thermally induced depolarization and thermal lensing using FK51 glass is demonstr

Faraday rotators with short magneto-optical elements are created and experimentally studied. The magneto-optical elements are made three to four times shorter either by cooling them to nitrogen temperatures or by increasing the magnetic field. These

It is shown experimentally that cooling of a Faraday isolator to liquid nitrogen temperature considerably suppresses the thermally induced depolarisation and reduces the thermal lens. This leads to an increase in the maximum average laser radiation p
