Damage-threshold performance of Al2O3 films under high-repetition-rate 266 nm ultraviolet picosecond-laser irradiation

Key Points

• Damage-threshold performance is crucial for alumina films when subjected to ultraviolet irradiation.
• The study indicates that at high-repetition rates, specific alumina films exhibit varying damage thresholds.
• Assessment using ultraviolet picosecond-laser strongly highlights the resilience of the films under testing conditions.
• Implications suggest further exploration of alumina films in laser applications may enable improved technology options.
