The invention discloses a high-power laser image transfer space filtering device. The device is characterized in that the device comprises a frequency division lens, a recovery lens and a filtering small hole, wherein the frequency division lens and the recovery lens form a confocal optical system; and the filtering small hole is positioned at the focal point of the confocal optical system between the frequency division lens and the recovery lens. The device can realize image transfer by adjusting focal distances of the frequency division lens and the recovery lens; and the host material of the filtering small hole only absorbs few laser power, so that the filtering small hole is not required to be subjected to water cooling, the structure of the filtering small hole is simplified, the damage threshold is improved, the possibility that laser burns the filtering small hole is basically eliminated, simultaneously by adopting the scattering effect on laser beam of the roughed surface of the filtering small hole, the high-frequency component energy of the laser beam can be rapidly reduced, and the low-frequency component energy is hardly changed, and a low-pass space filtering function is better realized.
