Popis:	We proposed a technique of tunable plasma narrow-band filter (PNBF) to generate high-power narrow-band pulses based on a plasma mirror and pulse chirp. PNBFs have an ultra-wide free spectral range, high damage threshold, and accurate wavelength-tunable function, and tunable sub-nanometer pulses could be achieved by controlling the pulse chirp. The feasibility of the proposed technique was verified by both simulation and experiment. Three ~0.6 nm bandwidth pulses centered at different wavelengths were obtained respectively, maintaining good near and far-field beam quality. PNBF is expected to be an effective technique for high-power tunable narrow-band pulse generation with high-power ultrafast lasers.
