【英文摘要】 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% andΔλ(R≥99.00%)=75nm, respectively, for the broadband resonator mirror. For the mirror with the dual-central wavelengths, R=99.69% andΔλ(R≥99.00%)=59nm f... |
