The article presents a demonstration of optical isolation (one-way propagation of the laser beam) for the beam of the Bivoj laser system operated at the HiLASE center. For the given parameters of 100 J pulses with a repetition rate of 10 Hz, this is a world-unique device on which the optical isolation of a pulsed laser beam with an average power of 1 kW was demonstrated for the first time. The isolator uses the non-reciprocal Faraday effect and achieved attenuation for the back-reflected beam at the level of 30 dB for a period of 1 hour (approx. 36,000 pulses) of test run.
