Abstract：
The cavity mirrors of the storage-ring free-electron laser (SR-FEL) at 355nm and 248nm central wavelengths have been developed with the technologies of electron-beam evaporation deposition and ion-beam sputter deposition. The mirror coatings consists of “HfO₂/SiO₂+Al₂O₃/SiO₂+M-SiO₂”.The absolute reflectance and frequency-tunable range at 355nm are R=99.45% and Δλ(R≥99.00%)=75nm, respectively, for the broadband resonator mirror. For the mirror with the dual-central wavelengths, R=99.69% and Δλ(R≥99.00%)=59nm for the first band at 355nm; For the second band at 248nm, R=98.21%, Δλ(R≥99.00%)=9nm and Δλ(R≥98.00%)=51nm.
