Abstract
The optical detection of a nanosecond laser pulse in transparent ferrimagnetic single crystals of yttrium iron garnet and yttrium orthoferrite in the IR range at room temperature was experimentally studied. A linearly polarized neodymium laser (wavelength 1.06 μm) operating in the Q-switched mode was used as the source of electromagnetic radiation. The pulse duration was about 20 ns, and the peak power ∼10 MW. It was found that the ferrimagnetic detector has a sufficient response time to detect nanosecond laser pulses. The amplitude of the detected signal strongly depends on the external bias magnetic field and correlates well with the nonlinearity of the static magnetization curve of the ferrimagnetic crystal sample used.
